I hope you're right. ...but did Apple upgrade the processing of the 3GS when they released the iPhone 4? Negative. Past patterns contradict your theory.
No but when Apple released a Verizon iPhone they did change the inner design of the case, the way the glass is held in is different and the way the back plate is held in is different.
So Sprint, which is 100% getting the iPhone 4 this year, will too get a custom design phone, Looking 99% identical in every way as the AT&T and Verizon iPhones but having a different logic board and inter parts ect ect.
The pictures of the leaked N94 iPhone 4S are nothing more than a Sprint model iPhone 4 rear glass housing.
I rip all flavors of iPhone apart every single day and the leaked N94 part is identical in almost every aspect of the AT&T and Verizon iPhone 4.
The iPhone 4 thats currently in China uses GMS technology. Thus it is basically and AT&T iPhone 4.
The talking with China Mobil for the iPhone will use a new LTE technology that Sprint is currently running multiple phones on the LTE network in the USA. So that means CUSTOM CHIPSET, CUSTOM LTE IPHONE 4.
So when you have a potential 1 BILLION subscribers of the iPhone 4 coming in the next months, Apple will be glad to bend over and kiss anyones combined butts with a 700 million to 1 Billion potential subscribers.
Theories on the iPhone 5 designs being nothing mearly then an iPod touch 5th gen.
Imagine this.
iPod touch 5th gen and iPhone 5 being almost identical in every aspect.
Add a date connection and a contract with a carrier and you have an iPhone 5.
It makes much more sense for a huge company like this to streamline their iPod and iPhone production wise. Saves you billions on the back end.
