Hi all,

I upgraded my friends 3Gs so he could unlock to the iPad baseband but I don't get any signal bars, I assumed ultrasnow would fix with 1.2.1. But it's same issue.

I can use the net and speedtest was 1.9mb so it's running normal for the network but can't text or call. Anyone any idea?

Software is 4.3.1 baseband 06.15.00
 
There is no unlock for 4.3.1 right now. What you need to do is to downgrade to 4.1 or 4.2.1 and then unlock with ultrasnow. There are tutorials on how to downgrade.

Please note that unlock is base on the baseband and not firmware version. It doesn't matter which firmware version as long as your phone baseband is compatible or can be unlocked by ultrans0w, then your phone can be unlocked.
