My iPhone had 2.01 firmware when I bought it (second hand) and the problem was just there ...
"All I could see was my Choose Network circle going round and round non stop, but it can't find anything at all"
So I tried to flash my iPhone with 2.02 firmware by Pwnagetool (Mac) but the problem is still here
@Doerrfan : Are you sure about reflashing baseband?
anybody out there knows a fairy trick?
sorry for my poor english and good night
