Greenpois0n iPhone 4 can't activate ATT network

[Canezmd]

iPhone 4 used tiny umbrella to preserve baseband 01.59.00. Upgraded to 4.2.1. Jail broke with greenpois0n, installed Cydia with redsnow. Restored the phone..... Carrier section says "no service"

Under settings > about... It says network : not available carrier : not available

Anyone have this problem?

Yes I had this exact problem. I ended up restoring it again and all was well.
It seems sometimes the jailbreak doesn't go right.

So basically restore it again and then re jailbreak and you should be fine.


PS you could also try to reset network setting but that didn't work for me...
