O2

Hi there, I was wondering if it's possible to change my device's name in My O2. Right now it's just my phone number. I seem to recall there being an option to have a custom name for it years ago, but it's disappeared.

I'm sitting pretty using a BB Curve 8520 right now, and I've noticed how most other UK carriers have switched off their BIS servers. If O2 will do the same (which they most likely will, unfortunately), does anyone have an idea of when it might happen...

I have absolutely no clue on how to release my BlackBerry's PIN so I can use BIS on another device. Is there a way that I could do this?Model: Bold 9790O2 Pay As You Go (Classic)(Yes I do have the BIS Bolt-On)
