After installing 3.0 I get zero bars, no service.

Anyone else? Any idea why?
I will try a full restore, then a update again. Wish me luck.

I have a 3G and I'm using a pay as you go sim card. No problems before updating. Had it jailbroken and unlocked before. Don't care about the unlocking right now.

Funny because I am actually getting better service it seems.

Update.
After a full restore to factory settings, then upgrade to 3.0 thru iTunes, all seems to be working. I get 5 bars now, will wait a couple days before jailbreaking.
