I have recently updated my already jailbroken iphone 3gs (new bootroom) while preserving ipad baseband (06.15.00) from 4.2.1 to 5.1.1 with sn0wbreeze-v2.9.6 and then unlocked it via ultrasnow. Can I use redsn0w 0.9.15b3 to update to ios 6.0.1 or do I have to downgrade the baseband first and then update to ios 6.0.1.? Also, will ultrasnow unlock my iphone 3gs after installing ios 6.0.1? |
