I would say iphone5 but I don't k ow when it will come out. I heard like end of sept u can buy and it ships early oct. The difference between the iPhone 4 an iPhone 5 is a lot I believe from rumors I heard such as better camera new slicker design ,battery life,and much much more. When the new update comes out well when iPhone 5 comes out that's when update will be out. This will make iOS sloop much better then it already is. For android phones idk because I'm not really fan of them (not trying to be a hater). I had found a mytouch4g and that was sooo slow. Like some of the htcs look pretty good like thunderbolt I believe.
