I do not have a great deal of knowledge something like cellphones, but I know a little so please don't trademark fun of this question.
I own a iphone right now and i hear 3G will come near iphones soon. does that mean in poor health need to find a new iphone if i needed 3g or could i just win 3g through an update?
Answers: Nope, neither. You will have to completely buy the unmarked 3G iphone again from the beginning. Unless your contract/tariff have come to the 18th month end and you are allowed an upgrade.
