This is doing my head in!!!!! Why can't I get a non-T-Mobile UK SIM to work in my 2g iPhone??!

  • Downgraded from 2.1 to 2.02 - T-Mobile UK works - no other SIM works


  • Downgraded from 2.02 to 2.0 - again T-Mobile UK works - no other SIM works


  • Uninstalled iTunes 8 & reinstalled iTune 7.5 and downgraded to 1.1.4 & ran Ziphone - again T-Mobile UK works - no other SIM works


  • Restored to 1.1.4 factory settings & ran winpwn 1 - again T-Mobile UK works - no other SIM works


  • Ran Kiphone & downgraded baseband - again T-Mobile UK works - no other SIM works


  • Upgraded everything to current status (iTunes 8, firmware 2.1) & ran Quickpwn 2.1-1 - guess what? T-Mobile UK works - no other SIM works!!!!! Arghhhhhhhhh


***For all of the above I've run the unlock/jailbreak 3 times - with no SIM, with non-T-Mobile UK SIM & with T-Mobile UK SIM & every time only T-Mobile UK SIM's have worked***

I've even tried it with a different T-Mobile UK SIM (my wifes) & hey presto, it recognised that SIM!!! It appears that my iPhone is addicted to T-Mobile UK!!!!

I'm beginning to think that the T-Mobile UK fairies/gremlins are living in my phone

Has anyone else encountered anything like this?
