Clever piece of software, pity I need a babelfish to help with the translation

Good news is I've managed to:

• Reveal the hidden network menus to lock it to 2.5G (900/1800)
• Delete the locked web sessions

Still outstanding is the email issue where the gprs session for email appears to be hard-coded to "3". If this is is locked to the first web session it can probably be edited.
