i bought a blackberry and it has the enterpise activation on it i have tried rewhipping it and reset factory settings and its still there and when i view IT Policy it says no services

Ignore it. The option is supposed to be there. You don't need to use it unless you're going to activate your device on a BES.

You will need a BB data plan to have BIS/email access and also access to other RIM services, such as maps, Facebook, Internet, BBM., etc.

sorry i shoulda made this clearer i bought the phone off kijiji and the person had the enterpise activation with another carrier but its unlocked and i cant get in without the persons username n password. is there anyway?... will removing the IT policy method work?

Enter the password incorrectly until the device wipes itself.
Then you can set your own password and follow the steps to remove the IT Policy.
