The implementation of iChatAV on an iPhone will certainly spell the end of the cellular network.
And that's a good thing.
Let's look under the hood of the iPhone - it comes complete with quad-band network compatibility for all present environments, bluetooth, Edge and Wi-Fi. It's the latter that interests me the most.
With international roaming tariffs of anything around £2.50GBP per minute (@ $5US), the logical alternative would be the use of high speed broadband for voice communication - an example of this is Skype.
Skype has cheap rates (NEGLIGIBLE in comparison to cellular), reliable and accessible going down the route of broadband chat. The advent of 3rd party software for the iPhone has given the makers of Skype yet another platform to excel and dominate.
But insofar as VIDEO communications, iChatAV shows its class.
Apple's in-house proprietory software SHOULD take the iPhone to a completely stellar level. In his keynote speech last year, Steve Jobs indicated a fleet of iPhones will be released with various specifications over the coming months. A good indication to us that the current iPhone design will not remain stagnant for long - if at all.
With phones such as the Nokia N series, with still/video cameras front and rear, the technology currently exists to include such devices into units the size of the iPhone. I predict the NEXT generation of iPhone will have such cameras included as standard - thus offering V(ideo)OIP.
Cities such as Norwich in the east of England have launched pilot schemes bringing high speed wireless internet to the masses - for FREE. Considering the cost of upkeep, the slow performance and unreasonable price of the cellular network, the next logical step would be a nationwide roll-out of such plans.
Imagine being able with your iPhone communicating between 15-30 fps wirelessly to AIM and .mac users - anywhere on the global broadband footprint - and all for free... Say goodbye to the ridiculously high prices of our mobile networks.
