Now that we know the O2 (Germany) Pre does indeed work on some international networks, I thought I'd start a thread where we can collect some info on that.
Someone posted a list over at infocenter. However, I doubt it's for real:
http://www.palminfocenter.com/forum/...gs-db3-t46893/ Swisscom's on there and that provider definitely isn't supported at the moment (tested it myself).
Important info: while the list was / is being compiled to the best of my knowledge, I can't personally verify all the entries. So they're without any guarantee for completeness or correctness. Also: the list is only valid for O2 (Germany) Pres. Reportedly, devices sold in Ireland and the UK behave differently.
