How to block a phone number on your cell?

Having worked in the wireless biz for longer than I should have, I will tell you there is no way to block one specific number from getting through on your cell phone. You can do this with a landline phone. I can't remember the name of it, but call your telephone company. I did this once a while back, but it involved putting an extra feature on my calling package for a small monthly charge. Once I programmed this person's number in, they were unable to get through to me and would instead receive a message telling them they were blocked from placing calls to my number. P.S. Even though you can't block specific numbers on your wireless phone, you should still call your carrier so they can make note of the harrassing calls in their system. You can also change your wireless number... which is a pain in the butt if you have a lot of people with your number, but if the harrassment is bad enough it is worth it. OR To block number(s) from cell phone you can use SONY ERICSSON models. There's feature with it to block numbers!!!...
