When they will make iphone 4g?

IPHONE 4g

If you mean the 4th generation iphone, then probably next summer since the 3rd generation is supposed to come out this summer. If you mean an iphone on a 4g network, at&t has yet to finish upgrading their cell towers and when that is fully complete and able to handle the iphone user traffic i'm sure they will release an iphone 4g. However, that date is completely unknown to the general public as of this time.

My guess and been keeeping an eye on it i know that is well comeout at jume or jully but i wish that it well comeout at july!
