I never knew you could block numbers via your Sprint account.
There are some third party apps that let you block numbers (ex: Callsblocks, Call Blocker Pro) as well. From what I gather, they just pickup/hangup or send to VM any calls you have on thier list.
well it depends on what blocking method hes asking for.. im talkin about txt message blocking... on your sprint account on the right side click on text message options and its there
trust me you can do it on the phone also. i did it on my GF sons lg rumor and on her lotus. i just didnt wanna call sprint and ask because we all know how that can be.
again this is for non blackberry phones im not lookin for an app its just a sequence of #s sent as a text then a text is returned to you confirming the phone number is blocked
