hello i have the blackberry 8310, it use to be a business phone but now i am using it as personal and put my personal sim in i can receive email but can not browse the web i have been to o2 and they are saying it because the business have blocked it you need to make it personal not business how can i do this myself

If you are absolutely sure that your company is OK with you having the BlackBerry for personal use only, here is a link that should help. Follow the instructions carefully.

Remove IT Policy - BlackBerryFAQ

hello again i have had permission to do this now i followed the instructions on that link which was very useful thanks but when i got to step 6 and started desktop manager again it had a error on policy.bin file could this be where i have got the right desktop manager and can you send me a link so i can get the right on eg:Ensure the Blackberry Desktop Manager is installed using Blackberry Internet Service, and not Blackberry Enterprise Server. If you are unsure, it would probably be a good idea to uninstall the Desktop Manager and start again.

this was the only bit i wasn't sure on thanks for the help
