I have a blackberry 7520 and when I try to make a call from my address book I get a message that says "the number or code you are trying to dial is invalid" I know the number is right because I can dial from the main screen just fine. For example if I dial 555-555-5555 from the main screen it works fine and the call is made. If I click on Mr. Jones in my address book and his number is 555-555-5555 it won't work.) Anyone know whats up with that??? It also does it on speed dial calls as well. Again, address book and speed dial does not allow me to make the call. Dialing from the main screen works just fine. Thanks
