3GS unlock help

[lostgirl85]

hi, dont know if anybody can help. Got an iphone 3gs and it was unlocked and jailbroken until three wks ago. Someone updated it to 4.3.5 by mistake and now it locked again. Dont know what to do. Paid someone online to unlock with redsn0w and it did install cydia and i installed ultrasnow. But everytime i go to choose my carrier, it tells me that its unable to give me a list to choose from and is just set on automatic. I says no service and does not recognize my SIM card. Dont know what to do. I'm thinking of restoring to factory setting but would that bring it back to 05.12.02 coz now it 05.16.02. Any ideas?

4.3.5 in a tethered boot. Check Tiny Umbrella (info in link). What SHSH blobs do you have??
If none are available, 4.1 is ok atm because Apple is approving it.

Your current baseband can not be ultrasn0w unlocked and can not be downgraded.
If you want to unlock, the iPad BB update is needed. It's breaks GPS , but it unlocks.
