Ultrasnow 1.2 not working with 4.3 3gs

[NBG]

I have try to upgrade my iphone 3gs with 4.3 custom firmware, install ultrasnow, but I cannot get network. I downgrade to 4.2.1 and it works. I made custom 4.3 firmware with snowbreeze, and downgrade with pwnage.Also youtube not work with snowbreeze 4.3 custom firmware, so beware of this issue.

Yes the 4.3 "jailbreak" is unofficial and unstable.

I sn0wbreezed an iPhone 4 to 4.3 while preserving the 01.59.00bb earlier and sn0wbreeze 2.3b1 says that mobile substrate isn't working and that ultrasn0w isn't working either.

Right, 4.3 isn't officially jailbroken so don't expect anything to work. And if something does work, its just a bonus and you should be surprised its working, not surprised its not.

Your baseband will remain 05.16.01. It is not possible to downgrade a baseband.

No the baseband will not change unless you use redsn0w 0.9.6rc8 to install the ipad baseband. If you NEED to unlock then install the ipad baseband, but keep in mind that you will lose gps, the maps app will work fine though.
