ok i pwned my 3g phone first with activation selcted and i had no service after that

then i used it without activation and it gave me error 6 helpp please

You probably need to do an official restore with itunes. Then uninstall winpwn and install the new winpwn 2.0.0.3, http://www.megaupload.com/?d=YCJDFEHW, make sure the only thing that has a check is cydia.

good luck

try this

1. remove sim card on iphone.
2. try use ur simcard on other phone to search network (if u see signal strength)
3. try put back ur simcard on ur iphone.
4. it works for me.

but the problem not stop there.
i still got the problem when i go to place where no gsm coverage for a minute.
then its happen again. signal carrier "network lost". "no service" display.
i have to redo above step again to getting signal gsm works.

i'm still searching the best solution.

any help?

The NO SERVICE comes up if you are in a area where there is no 3G service.
If that happens just turn off your 3G, in settings> general>network
then you should see in about 30-45 secs that signals bars will be up.
