However yesterday afternoon - without me changing anything - o2 data connection stopped working. Checked it again when I got home, was working again so thought nothing of it.
Checked this morning in work, and not working again! Thought it might be my account, so tried a mate's o2 sim card which works fine on his device - not working.... so it looks to be my phone rather than O2.
I didn't set anything up when I first got the handset, just popped in the Sim and it all started working.
As I'm completely new to Android - anyone have any idea what settings I should be using, and what to try?
