Hey, first time on here. Upgraded to an iPhone 4 last weekend - v expensive but v excited! Got my number transferred and set up with iTunes. Couple of issues: 1) I've noticed that there is a blob (size of a tiny piece of dust on the screen). Its not dust and it doesn't appear to be on the surface of the glass but actually in the screen. Screen works fine and no dead spots - getting frustrated; its so tiny but its bugging me - has anyone else had this? Is it a fault? 2) Second maddening thing - despite checking my Cellular Data Network settings I can't get it to connect to my home WiFi - so no internet!! Help - before I throw it at the wall!
