I have the IPhone 2G and i am going to upgrade to the 3GS just wondering the price on this and if it will be any cheaper since i already have the whole IPhone plan on my account. i know i am going to have to get 3G but anything else?
When I purchase my iphone 3gs i will unlock it and go to tmobile. I heard that the iphone only works with tmobiles edge, what is the reason and when will the iphone work with the 3g. Also, will gps and maps work?
