I am having major issues with my UK GSM Pre's online gaming abilities!!

It will not let me play NOVA online even with a full 3G signal... just says "connection request failed" .... BUT it will play via WiFi no problem at all.

I can stream media e.g youtube over 3G no problem at all. Anyone suggest whats wrong with my handset??

The only other issue is that my phone number does not appear in the device info page incase there's a link?? i.e could it be a network issue or is it my hardware??

Thanks to all who respond with something plauseable!

FYI I am in UK on Official O2 WebOS 1.4.1 clean build with no tweaks at all and NOVA is my onle 3rd party app.
