I had a text from O2 which I thought was telling me I had been unlocked. Foolishly I upgraded my iPhone from its YellowSn0w jailbreak/unlock to OS 3.1.2. Then I found that my phone had not been unlocked… I checked the text from O2 again and realised it was not the unlock confirmation…

A few days later I phoned O2 to check on the status of the unlock and was told it would happen within the 14 days which has a few days left to go. On the 29th December nothing had happened. So I tried phoning O2 again and after a long wait I was cut off.

Today I finally got a text telling me I was unlocked and to put a new sim in the iPhone and connect to iTunes. I duly complied and iTunes told me the phone was not unlocked.

As I am off to the USA for a month I could not afford to go through the process again. Having upgraded the OS I had also upgraded the baseband which prevented me from Jailbreaking using YellowSn0w again. After a quick check I found that the Blackra1n and BlackSn0w jailbreak/unlock actually recommended using the OS/Baseband I had upgraded to. So a quick download and in less than 5 minutes my iPhone was jailbroken and unlocked. I can now put my US SIM in it and not be clobbered for stupid data roaming charges.

Now looking back on the O2 problem it may well be my fault as I have switched my 3G and 3GS sims. However if that is the cause then I would have thought that O2 might have picked this up and warned me rather than letting me try to go through the unlock process twice and fail…

O2 – 2 strikes over 6 weeks. BlackRa1n – Home run in 5 minutes…
