no official unlock or jailbreak yet. But you can bypass the usb loop by inserting any universal sim or att sim. I always recommend you to stay away from update at least first 2 weeks , IF IF IF you rely in jailbreak and Unlock..  quick question what Baseband are you in?

You have to upgrade baseband to 6.... something like that. Use ultrasnow to jailbreak and unlock.

 it depends upon which phone, i mean 3gs or 4. if it is iphone 4 then forget about it except using turbo sim  still the problem is the jailbreaking. there is no unthetred jailbreaking for this version.  meaning everytime the phone restarts it stuck on apple logo and u have to activate using redsn0w which is painful.   if it is 3gs then use redsn0w 0.9.6RC16 and do use ipad baseband that way it will be unlocked. But i am not sure that there is unthetred jailbreaking for this version too.

Redsnow will jailbreak it. Download your 4.2.1 from iclarified. When you run redsnow, make sure you tick the iPad baseband, it will put your baseband to 6.15. When you're done you should have an app named cydia now. Open that, then go to manage/edit/add ultrasn0w to unlock it
