Hello, about a year ago I tried to go from 1.1.2 to 1.1.3 using a tool that I downloaded throught installer (I donīt remember the name). After I updated from 1.1.2 to 1.1.3 I started to have the grey no wifi and no bluetooth. After that problem I started to use Pwnage tool, and the phone work ok, but still have the grey wifi problem. Any way to fix this??? My phone is a 8gb 2G Iphone.
