Its sorted out...
CPW do open their boxes & in the case of the
![BB Icon](http://www.blackberryforums.com/images/smilies/bb_icon.gif)
they install an additional navigation package called CPW Navigator.
The reason my phone would not register, is because my sim had not been enabled for the
![BB Icon](http://www.blackberryforums.com/images/smilies/bb_icon.gif)
service. I called T-Mobile UK out of sheer frustration. The guy said the problem was due to my sim not having been enabled for the service. He told me he would enable it & to give it 30mins. 20mins later I received an email. I then tried registering on instantemail.t-mobile.co.uk again & this time no problems with registering.
The frustrating thing is that none of the errors mentioned anything about my service not being enabled... Instead it lead us down a path of potentially used handsets!
Anyway, to all who have helped & advised me I would like to offer my gratitude. Thank you all... You guys rock!
