my friend has an iphone 1g unlocked and he might be willing to trade for my itouch 2nd gen. i can basically use his iphone as an iphone and a phone at the same time, but the problem is, there's a few things im not sure about. first, i know iphone 1g cant upgrade to os4, and if someone could clear up the advantages and disadvantages of having os4, then that'd be great. second thing i want to know is what are the speeds of both of them? i heard the processing or the ram or whatever might be diffeernt and i want to know what they are. thanks guys!
