Iphone4, 4.2.1 unlock possibilities for trip to Europe?
I have an iPhone 4 on 4.2.1. I have AT&T but am traveling to Europe in a few weeks and would like to unlock and use my vodafone sim card. I see that people are not recommending the new redsn0w beta jailbreak for use with Ultrasnow. Are there ANY options to unlock, such as downgrading my software/baseband?
The unlock part of this question has been asked and answered many times here on this forum.

Your only chance was if you had thought about unlock when you were running iOS 4.0.2 or lower and taken precautions to upgrade in a way that prevented your baseband being updated. If you did not take precautions then (or if your iPhone came with iOS 4.1 or 4.2.1) then you have no option but to wait.
How long you will need to wait for a new unlock - I don't know. It could be a month or six months...
