The infamous iPhone Dev Team has announced that they soon will be porting the iPhone 4 unlock to carrier unlock tool “ultrasn0w” after having identified an exploit to defeat the anti-ultrasn0w “tambering” checks in iPhone4 baseband to unlock iPhone 4 few days back. Currently, the team is in the process of fine tuning the payload to make it as quick to load as possible.
The team has had a series of successes with the carrier unlock on iPhone4 (#1, #2, #3, #4, #5-video). We’re fine-tuning the payload to make it as quick to load as possible (and making sure it remains crash-free of course!).
Most likely comex will be releasing spirit userland jailbreak to jailbreak iPhone 4 after which software solution Ultrasn0w can be used to unlock iPhone 4. With an unlocked version of iPhone 4, users in US can easily use prepaid SIM cards other than AT&T and comes handy when you plan to travel outside US and still want to use the iPhone.
But no ETA was cited for iPhone 4 iOS 4 unlock software. Stay tuned for more updates!
