OK so I have an ACTIVATED iPhone purchased in the US (on AT&T's 'pay as you go' plan). Firmware is version 1.1 I'm now in the UK and I used appsnap (jailbreakme.com) to jailbreak the phone. Then I installed FreeBSD subsystem, Community source thing, and OpenSSH. Then I installed anySIM. All seemed to work fine. I put my UK (Vodafone) SIM card into the phone, and ran anySIM. Followed the prompts on screen. anySIM reported that the unlock was successful. However, I am not able to use my unlocked phone. The phone said that the SIM had been changed and that I needed to connect to iTunes. I connected to iTunes (version 7.5) and it said that "There is no carrier that supports the installed SIM Card in the iPhone." I thought maybe the problem is the version of iTunes (7.5) so I downgraded my iTunes to version 7.4.2 I also powered down the phone, then restarted it. Now the phone says that I must connect to iTunes in order to activate it. Seems that it is no longer activated. When I connect to iTunes it says I cannot activate the phone with version 7.4.2, I must upgrade 7.5... Any advice gratefully received!
