Hi. I am considering buying an iPod Touch or iPhone but I really don't know which to get. I can definately afford the Touch now but the phone would have to wait a while. Now im not really farmiliar with what sort of apps are avaliable for either device although I plan to have a good look around the apps store. I presume I will be using lots of games. I like the idea of the iPhone but its just whether its worth the big price tag or whether I should just get an 8GB Touch. Is there a big difference between the 2nd and 3rd generation touch besides storage and is there a large difference between the 3g and 3g s iPhone? Basically what im asking is what are the main differences besides the obvious fact that one isnt a phone?
