No, you can only get 4G service on 4G compatible devices. It is possible that the next iPhone released will be 4G compatible although that is still unknown at this point.
If you mean,' Do iPhone 3GS's have Verizonservice?'No, not anymore, as of 17/10/2011 you can only get the iPhone 3GS on AT&T!
There is no such thing as an iPod 4S. The iPod 4G stands for iPod 4th Gen. Such as iPod 3G. There is no such thing as iPod 3GS. There is an iPhone 4s and an iPhone 3Gs. There will never be an iPod with an s. : )
iPhone 3gs are more roundish and without Siri. The edges instead of being straight are round. The iPhone 4g has square edges without Siri. The iPhone 4s is just like the 4g instead it has Siri. The iPhone 5 is longer and has Siri. The iPhone (original) has round corners and is small. Same with the iPhone 2. If you have a iPhone or iPhone 2 you can replace them. Also, the iPhone 3gs is not out so you cannot buy it anymore. Only the 4, 4s and 5 are out. They will be getting rid of the iPhone 4 soon.
iphones are 3g,4g and 5g is to be introduced in india
no No, the general idea of Apple upgrading the iPhone, was to make it BETTER. iPhone 4 has a HD Retina screen, can have a facetime call, Gyroscop, apple A4 chip.
unlocked only means it can be activated on any service, not that the phone is any better, when the iphone came out it was only available on one service, unlocked means you can activate it on any service
