Hi Guys

I just ordered the new iPhone 3Gs (bought 3G without contract...but still simlockes) now, i wanted to make the phone ready for ebay.

i had 2.2 running smooth...only jailbroken...now for ebay i wanted to upgrade to 2.2.1 and JB and unlock (better resale price!?)
anyhow... i am stuck on 2.2.1 with the 02.11.07 modem firmware (so, no yellowsnow) and i can't get any signal...well it shows 1 bar (no carrier name) and then changes to no network (or however it is calles in english)...

hay anynone got a clue how to get it to work...and unlock it?


thanks
