I have one (iphone4 32GB) mate, top top phone i was one of the smug people saying you could get the same phone for a fraction of the price the iphone was. Simple truth is mate you cant, its a thing of beauty, increasees productivity and for fun games, entertainment, music and staying connected there nothing better, its more like a mini laptop then anything and the apps are fantastic, and you will find your own favourates.
I asked myself would i use it that much before i bought and wheather i really needed it, truth is i started doing loads of stuff on it i never would have dreamt of on a different phone, do it mate you wont regret it.
No probs with the reception or making or getting calls, i think some left handers had probs.
