Today, when we think of iPhone client applications (app) what comes to mind are iPhone client SIP applications. This is because the capability to access voice over Internet protocol (VoIP) is a relatively new development for the iPhone. SIP (session initiation protocol), a powerful multimedia protocol, is far from new and applications for other platforms have been widely used for a long time. In the iPhone client application world SIP has not be widely available until recently. This is due in large part to Apple’s reluctance to support third party development since widespread use holds the potential to erode AT&T’s traditional cellular talk time market share. Lucky for users, iPhone client applications that allow for telephony via wireless networks (wi-fi) are here now. Skype, for example, recently announced its very own iPhone client app. This tool is actually available for download from the Apple store. There are many other SIP iPhone clients available for download as well, some from the Apple store, others from third party sites.

The availability of iPhone client SIP over wi-fi is a compromise solution that allows AT&T to retain its traditional cellular talk time market but gives users access to VoIP. While it may not be a perfect solution, it is a welcome one since iPhone users have been demanding access to VoIP since the introduction of the iPhone in 2007. SIP iPhone client apps seemed slow in coming but are now bursting on the scene and there are plenty of different VoIP iPhone clients to choose from.

If you are new to the world of Internet telephony you may not understand why having iPhone client apps for SIP is so important to users. The biggest appeal is the potential to save money. Since SIP/VoIP can help you avoid using traditional cellular minutes and make long distance calls to virtually anywhere in the world without paying toll charges, the potential for savings is huge. This technology is already widely used in the non-Apple arena so iPhone users were eager to get caught up.
We have only discussed iPhone client apps that have to do with talking over the telephone. There are many other types of iPhone client apps as well. When you use social networking sites such as Twitter or Facebook you are using an iPhone client app. You are also using an iPhone client app when you instant message or use WordPress for iPhone. The list goes on an on and it continues to grow. If we remember how new the iPhone really is, it becomes apparent that we have just scratched the surface of what is possible. We should also remember that most iPhone client apps that have been developed are based on 3G technology. We can only imagine what may happen when 4G is put in place on a wide basis.

It is an exciting time to be an iPhone owner. New, imaginative, and useful iPhone client applications come onto the market every day and protocols such as SIP are just opening up. New applications will continue to add functionality and creativity to the device. So as you try out new applications, don’t get too comfortable. Something newer and cooler is sure to be on the market soon.

The summer of 2007 saw the introduction of the new generation of mobile multimedia interactive cell phones with the release of Apple’s iPhone. Crammed into a package only 4.5″ inches and weighing less than 5 ounces, the Apple iPhone offers users so many features the company offers video tutorials to help customers learn all the things it can do for them.

Contained just within the phone functions are such pro-business features as call conferencing and merging, hold feature, caller ID and the ability to integrate with other cell networks. The iPhone offers voice mail listings without having to access the actual Voicemail and one can pick and choose between calls rather than have to move through them sequentially.

Due to the popularity of ringtones, it was only a few months before Apple upgraded to ringtone functions. By partnering in this feature with iTunes, users can custom design their own ringtones from purchased songs through the iTunes network or the Apple GarageBand software. These ringtones can then be used not only to alert one to an incoming call but can be associated with specific alarm and notification features as well.

Text messaging has been made easier with the implementation of a virtual keyboard on the touch screen. For increased accuracy the texting program includes such aids as predictive word capabilities coupled with automatic spell check and correction and a dictionary that allows you to add words as needed to help it understand topic related jargon, names and special purpose words and phrases. The virtual keyboard has been made a bit larger than previous attempts at this virtual technology and, with two-way orientation, is at its best in landscape position.

As well as superb telephonic utilization, the Apple iPhone has the capability to access e-mail clients through both IMAP and POP3 servers. Both Yahoo and Gmail offer a program for access from the iPhone and by mid 2008 are planning to upgrade to sync with both Apple’s mail application but with Microsoft ActiveSync to connect with Microsoft Outlook and Entourage. The e-mail capabilities include HTML acceptance for graphical e-mail that can include digital photographs and graphics and can embed pictures in outgoing mail as well. Portable Document Files (PDF) as well as Word and Excel documents can be attached and viewed on the iPhone screen.

With a picture being sometimes more informative than any amount of verbal description, the iPhone does have a two megapixel digital camera onboard and the output can be copied directly to an e-mail. The iPhone does not, however, offer video camera functions.

The Apple iPhone was originally released with the Subscriber Identification Module (SIM) card locked into the AT&T network exclusively. However it did not take long for hackers to find a way to unlock the card for use on other networks and now nearly a fourth of the iPhones sold in the United States are not registered with the AT&T network. While originally designed to block the multimedia and web access functions without an authorized subscription; this too has fallen to the hacker’s craft and various software programs and modification cracks have emerged to free the access to these features outside the AT&T network.

These features make the Apple iPhone a powerful business asset even without even beginning to discuss the many other multimedia and web accessibility features that have made the iPhone worthy of Time magazine’s Invention of the Year award.

Apple is rumored to be in talks with Verizon for 2010!

The once believed rejected to have it’s first chance at the iphone, Verizon is now claiming to be in discussion in Apple for it’s very own iPhone coming in 2010!

The latest Apple News points to it’s source, USA Today explains that Verizon reported entered serious talks Apple. The newspaper infers that the phone are able to have to be CDMA version, so that it’s compatible with Verizon’s existent networks. Such action would contradicts Apple COO Tim Cook’s own dismissal of CDMA go on week: When discussed about the iPhone making excessively justified the absence of CDMA model by declaring that a single, GSM phone model to produce than a CDMA model. Cook as well criticized CDMA by asserting it has no future, as most CDMA carries plan to phase out the technology in favor of the same 4G standard what will be used on GSM network.

More likely is a direct leap to a 4G. Verizon chief executive Ivan Seiderberng recently explained that a deal might be in the operates as 4G rolls out in 2010, and therefore experience at lest certain of it’s network ready for an iPhone CMDA version by then.

However, if Verizon does land an iPhone of its own AT&T may topple those ambitions in it’s own discussions. Although separate rumors reads this the up to date iPhone carrier is pushing Apple to extend it’s US exclusivity until 2011!

Any successful deal, no matter the network type, would likely be a serious blow to AT&T, which credited much of its ability to weather the ongoing economic crisis to iPhone sales and the resulting spike in data revenue. Aside from reducing incentives to launch massive, special upgrades to the network, a Verizon model would let those dissatisfied with AT&T’ s 3G coverage or its customer service defect to Verizon without giving up Apple’s handset.

In the world of telephony one of the hottest stories of the day is the long awaited delivery of iPhone SIP client applications. While there have been iPhone SIP apps for some time, it has only been in recent months that they have become widely available and easy enough for most of us to use.

It seems strange that with a phone as advanced as the iPhone that something as important as voice over Internet protocol (VoIP) would be slow in coming. But it has. The reason why is because of a strategic decision by Apple to prohibit the use of iPhone SIP over cellular networks. Instead, iPhone SIP was forced to use wireless networks (wi-fi) only. In fact, for some time, Apple even refused to support third party development of iPhone SIP applications. Luckily, Apple recently relaxed its lack of support and now iPhone users can even download iPhone SIP apps from the Apple iPhone store. Unfortunately, iPhone SIP still only works with wi-fi networks. Never the less, much to the joy of those who have long been waiting for iPhone SIP, there are now multiple options.

Why does anyone even care about iPhone SIP? Because SIP, or Session Initiation Protocol, enables users to make phone calls to any location in the world over the Internet and avoid using up expensive and valuable traditional cellular minutes. Of course, the very same reason users want iPhone SIP is the reason that Apple and AT&T have worked to prevent it. AT&T has feared that the ever increasing use of iPhone SIP will erode its profits from cell minutes. While the fear is probably justified, it is becoming less and less of an issue as Apple’s new willingness to support third party development of iPhone SIP applications has lead to the recent announcements by many SIP companies of big product launches. Skype, for example, recently launced services for iPHone. This is seen as an indication that more are on the way.

SIP technology is capable of much more than simply telephone calls. Many hope that application developers will take full advantage of the multi-media capabilities as well as simply iPhone SIP. Video calling, for example, is a real possibility in the future.

So what provider do you have to use in order to take advantage of iPhone SIP? The answer is, any provider that offers SIP. Fring is one popular choice as are Skype, SIPgate, and Nimbuzz. There are many others as well. You just need to do your homework and determine which plan is best for you.

No discussion of iPhone SIP would be complete without touching on the fact that with iPhone SIP you can now turn your iPod Touch into a telephone. Using SIP technology, you are able to access the same telephony services via wi-fi as you can on you iPhone. Now that is one big advantage.

While iPhone SIP may not be the perfect solution for VoIP, it is a darned good one. With more and more apps coming onto the market, it can only improve. Now you have yet another reason to be happy that you jumped on the iPhone bandwagon. So talk on. You aren’t even using your cell minutes!
