I have the iPhone 3GS 8 Gigabytes and noticed that in their manual that it works at 7Mbps.
3G network runs from 256 Kbps to 1Mbps, 3.5G network 3Mbps to 6Mbps wheel and 4G network 5Mbps to 12Mbps wheel.
* IPhone 3GS can run on 4G network? That Being is the 4G network -> 5Mbps to 12Mbps and iPhone 3GS -> Operates 7Mbps network?
>>> Like the iPhone 3GS has 7Mbps it works on 4G network?
