Well, kind of worried at first but decided to give it a try since it got lots of positive reviews.
Mine was Iphone 4 locked to Three UK. Been using Ultrasn0w for 2 years now but lately for the IOS 6 Ultras0w seem to support until ios 5.1.1.
Saw lots of signal problem for iphone 4 running on old baseband 1.59 at IOS 6. Decided to just factory unlock after waited for almost year for software unlock update. It was a bit late for the unlock but it actually worked for me. took more than 3 days to finally received the email your iphone finally unlock but it was worth it.
