A rip-roaring good morning to you all!
I'm in a good mood you see. Having spent hours trying to configure an O2 Xda mini which has a T-Mobile sim-card, I stumbled across a site http://www.phonehouse.de/ which has all the configuration details listed down in a simple easy-to-understand fashion for the three major networks. I thought I'd share it and maybe make someone else's life just a little bit easier. Try the site! If you have problems PM me. I'm in such a bloody good mood I'll e-mail the instructions if required. I don't want to take up too much space here.
BTW, I don't work for Phonehouse, have no connection to them and don't give a hoot about what they sell.
The Utimate Altruist,
