O2 wap problems

[Guest bergerboy]

Been using my SPV for the past month successfully with my o2 card and

regularly use it to surf the net.

Started playin with my phone at work trying to use it as a modem,

since then my phone won't connect to the web - starts to

connect then gives me a message - unable to view page.

I have checked my settings and they are still the same

Anybody got any ideas or had the same sort of problem
