I have a iPhone 2G - the first ones to be released. All is good and although i like the new iPhone i dont need it. There are now many many apps obviously being updated to iOS4 and im concerned that they might suddenly stop working on my iPhone - is this a valid concern as im holding off updating any at the moment (all work anyway)...? I remember one app stopped working around iOS 3.1.2 or something and i had to update firmware to get it to work again. This time i cant do that. Any advice / opinions?
