Just two days after it had brought back Jailbreakme.com from the dead, the iPhone Dev Team said Wednesday that it had completed an unlock that is compatible with the iPhone 4. As before, the phone must be jailbroken before it is able to be unlocked.
The unlock, called “ultrasn0w,” works with iPhone 4 baseband 01.59 and iPhone 3G/3GS basebands 04.26.08, 05.11.07, 05.12.01 and 05.13.04. The download is now available in the Cydia app store which is installed upon jailbreaking the phone.
Specifics of how the Dev Team unlocked the iPhone 4 were not given, unlike the Jailbreakme.com hack on Monday. That flaw, which has to do with how the iPhone displays PDF files, has triggered Apple to look into the problem although its unknown at this time whether or not the company plans to act.
I’d guess they probably will, considering this is how hackers are able to jailbreak the device, something which is now legal according to the US government, but still frowned upon by Apple.
So now that it’s unlocked, I’m curious: does it work on T-Mobile US’ 3G network? Maybe that’s our first clue that the rumors might be true!
