I upgraded my Iphone 8GB 2g from 2.2FW to 3.1.2FW. This was the first upgrade and the WIFI was showing correctly the connection. As my bluetooth was not working in the hope that can work if I downgrade to 2.2FW (but i could not do this). So I reinstalled 3.1.2

In the second installation the WIFI indicator was showing as it is not connected but when I try with safari to connect a site it was working.

Strange!

PS: All works has done with redsn0w 0.9.4
