Goodness, that old phone! I think I used it for about a year or two, never bothered to unlock it because: A. I didn't like it that much, and B. it played up in the very lightest drop of rain. Then O2 disabled the SIM, presumably because I hadn't used it enough, and they didn't even wait anywhere close to the 6 months or whatever their then allotted time then was since the last chargeable call to block it, so I only found while I was out trying to get a lift home. I haven't used O2 since. It made a good alarm clock though :laugh:
