Best way to unlock iPhone 4 (ATT) 4.2.1?

**brh986** · 01-29-2011, 08:16 AM

I have a new iphone, just brought it home from AT&T. I have not plugged it into the computer yet or done anything with it at all.

What is the best way to unlock it? I had a 3GS with 3.1.2 that I unlocked with Blackra1n and it was buggy as hell. I hated it so I thought I'd try an upgrade.

Can anyone please advise me so I don't screw it up.

Here's all the phone info:

Version: 4.2.1 (8C148)
Model: MC608LL
Modem Firmware: 03.10.01

Thanks

Any idea when 4.3 is due out. I searched with no good results. I just bought two AT&T iPhone 4 for TMobile. They both have 4.2.1 and 3.10.01 and would like to swap to them from my 3GS.

Why do people not see the sticky that says HOW TO CHECK IF YOU CAN UNLOCK? I dont get it? Every other post is when/how can unlock my Iphone4 with 2.10/3.10. I have been waiting since August and I know that when the unlock comes(if it comes) it will be posted on here.

Unlock is coming soon.
Apple released the date of iOS 4.3 today (11 March)

, so I think in a few days we might see an unlock appear.

**Diddyo** · 03-02-2011, 12:07 PM

Apple announced 4.3 today, said it is out March 11th (next friday)

probably see an unlock soon after.

**GodStang** · 03-02-2011, 12:10 PM
