I have an 8800 and it has the T-Mo (US) software installed, however I am using it on O2 in the UK will this cause any issues?

T-Mobile US has not issued the 8800. IN any event, feel free to install the O2 software onto it.

- Shut down Desktop Manager
- Download from the O2 site
- Execute the downloaded software
- Delete VENDOR.XML from your PC C: drive <-- very important
- Connect the BB and restart Desktop Manager

You got a link to the o2 site?
