I have a curve 8900 and i added the blackberry data plan to my o2 contract.
I set my email up but my internet(not wifi) did not work.
I rang o2 and they sed i had to register my handset with my imei and pin on o2email.co.uk.
When i did i restarted my handset and i could not send emails and i could only receive.
Any help Please! it will be much appreciated!
