Hello, I Hope this is in the correct forum.
I bought a blackburry 8900 from a friend its two weeks on and he got it on a o2 UK Contact...My 02 Pay&go Sim card works as far as making calls and texts but wont allow me online. Ive looked and cant seem to enter and settings.
After Contacting 02 the customer service advisor recomended this site After looking im still alittle lost. If i buy an unlock code it will take any sim but will this allow my pay&go 02 sim to work correctly (with Internet) in an already 02 handset?

Thanks Simon
