blackberry cellphone
How do I block person from texting or calling my cellphone?
I have the Blackberry Curve 8320 (T-Mobile)?

There is software block that can be bought, but it cost too much. Gradica keep unwanted visitors from reaching me. I telemarketers who calls and get text messages bizarre and just use sending text messages. Does not involve the police action, I asked my service provider and they said that there is no way possible to block numbers. Which sounds like an FIB! HELP! Thanks in advance.
