Last night I followed the instructions at http://www.iclarified.com/entry/index.php?enid=655 to unlock my phone. Sure enough in less than 5 minutes I had an iPhone that was working with a non-iPhone O2 SIM but there were a few funnies. 1. The home screen showed Installer but no other apps even though going into the uninstall section of Installer showed lots of applications installed. 2. When I put my original SIM back in Youtube didn't work and neither did Visual Voicemail. Any tips?
