I have an iPhone 1.1.2 OOTB UK. I have jailbreaked and activated it so that I can use a non-iPhone sim on my own O2 contract in the UK. On friday I will be going to france for a week. I was wondering whether anybody has had any experience with using their iPhone abroad using the non iPhone O2 sim. Any information would be greatly appreciated as the last thing I want is to cross the chunnel and end up with a useless iPhone. Especially as I'll be driving there with an N95 8GB user, there's alot of one-up-manship there. Thanks in advance.
