Wifi set up? It just connected straight to my router ater entering the password. To say I'd set it up makes it sound like I actually had to do something. I'm used to having wifi in my pocket because I've got an ipod touch, I can see it getting left at home most of the time now though.
This thing honestly smokes fuck out the iphone 3, I've not played about with an iphone 4 to confirm that it smashes it aswell but I suspect it does. The OS is much better, so much more customisable & especially now that I can download any app for free I'm well pleased with it. Didn't have to fuck about with jailbreaking etc. Just copy the app to the sd card then install it on the phone. Fucking quality. Piracy is %)
