i live in dubai ni have an iphone imported from UK.
it was running 3.0 jailbroken tryed to find ultrasn0w or whatever snow .. couln't find it in cydia... thought i'd update to 3.1.2 and blackra1n it .. so i did update from itunes to 3.1.2 (baseband changed to 5.11.07) but found that there is no signal (itunes says sim is not supported) then i downloaded ultrasn0w .. nothing changed.
then downloaded a custom firmware 3.0 and installed it with the help of iReb 3.1.2 ... again downloaded ultrasnow but still no signal.

shall i try to download the original 3.0 from apple and redsn0w it then ultrasn0w it? ?????
Bootloader v 6.04 !
if not possible .... will the turbosim thing will work??????


thanks in advance.
