ultrasn0w carrier unlock now available for iPhone 4

ultrasn0w carrier unlock for iPhone 4

If your iPhone 4 is locked to AT&T or another carrier, good news -- the ultrasn0w unlock is now available to set you free.

Those who ponied up full price for an international, factory unlocked iPhone 4 direct from Apple need not apply. Those who chose subsidies and the lock that came with it, get your Jailbreak on and head over to Cydia. If ultrasn0w doesn't show up immediately, search for repo repo666.ultrasn0w.com.

Version 1.0-1 of ultrasn0w works for:

  • iPhone4 baseband 01.59
  • 3G/3GS basebands 04.26.08, 05.11.07, 05.12.01 and 05.13.04

Remember, you'll need a microSIM card if you plan on jumping to another carrier, and in the US that means manually cutting down your T-Mobile SIM to microSIM size.

As always, Jailbreak and unlock will void your warranty and could cause other problems with your device. If you don't know what you're doing, don't do it. If you decide to go ahead, let us know how it works for you.

Those of you who unlocked your iphone 4, is it working on T-Mobile USA's 3G network?

elementbt says:

if you restore and get rid of the jailbreak.. does that remove the unlock as well?

Miktia says:

Worked for me without any problems and i live in Finland. Tested with other operator 3g network and worked like a dream. Totally recommend.

tomcat says:

After unlocking it, my virtual voicemail is not working!!!!!!!!!! Anyone have the same problem, is there a fix?

Roger says:

Can someone who has jailbroken their iphone4 and switch to TMO confirm that it works on TMO 3G??? If so, I'm getting one....

Max Power says:

Works perfectly on the Rogers iPhones; both 3GS and 4. Telus and Bell sims work on it as well as Fido.

Oskyriver says:

Ulocked jailbroken wanted to erased personal data, before selling.reset settings and after that phone won't start stuck on apple screen. Help

Max Power says:

Google DFU mode. Same thing happened to me and DFU mode worked after a few tries. Don't worry. This happens to a lot of people. Make sure your iTunes is the most recent version too. That was the final missing piece of the puzzle for me.

Jared says:

does this work for a verizon carrier?

Paul says:

Does it matter if firmware is V.4.0.2? I unlocked on with V4.0.1

Benny says:

Have a verison sim card? Give it a shot.
