"Reset Network Settings" ruined my UNLOCK?!

[ryefield]

hi
I have iPhone 4 32 gb running OS 4.0.1, jailbroken (Limera1n) and unlocked (ultrasnow).

I accidentally reset my network setting, the phone rebooted and when it came up again my unlock seemed to be gone: I gent no signal bars and can't make calls. "voicemail" key in phone app is dead.

in general\network i don't have "carrier" at all but in "about", however, it does still mention my local carrier under "carrier".

I tryed re-installing ultrasnow on cydia, didn't work.

carrier bundle missing? limera1n-ultrasnow collision?

please help i need the phone!

thanks!

You can restore to 4.1 while running Tinyumbrella so you can maintain your baseband.
Then JB it and install ultrasnow from cydia.

If you've got a Mac, you can use pwnage and create a custom .ipsw. Check iclarified for instructions.
