iPhone if you know enough to fuck up a phone and don't know how to fix it if you're given more access than you need.

android if you're knowledgeable about technology and can fix your own shit, or at least know how to google shit.

if all you're going to do is 'check email' 'browse the web' 'play games' get the iPhone
if you're going to VPN, remote desktop, free wireless hotspot tethering by FoxFi - in Market (through a proxy so provider can't see you tethering) then get an android
