Ie if I'm at work can I stop the emails I receive through to my blackberry - its annoying having them come through to the BB when i'm sat at my desk with them coming directly through to me...
Don't know if this will work, but you could go into manage connections, choose Mobile Network Options, and set data services to off. This might allow you to use the phone but not email, SMS, etc. May be worth a try
Depending on your provider you should be able to just turn the data part off as stated above. Some wont let you because they use the same thing, but some you can have just voice on and not data if you wish. Otherwise, thats a big fat no no.
