Hi i feel pretty dumb asking this but i looked for ever now and can find nothing about what this PIN number is that i see in some peoples signatures.

i am assuming that it is used for some type of messages.
I have a BB 7100t with t-mobile and my PIN is 202c4f5c

thanks guys

Pin messages are messages sent directly to the bb. Not like email messages. every phone has a pin message.

Your PIN is something that identifies all blackberries. Everyone has a different one, kind of like a serial number. You can use this to send messages to other BB folks and they can reply, kinda like texting with BB, just for BB.

does it cost the same as a text message?

I believe its free, don't quote me on that though, I have Nextel, and I haven't seen any charges for it, but I got unlimited everything.

Thanks wallace. does anyone have t-mobile that knows how much it costs?

Hope it don't cost ya, cause I already PINed ya....LMAO!!

well i have unlimited text so if it is like a text that would be awsome.

It comes out of your blackberry data bucket...it's not billed per-message like SMS

since we are one this topic of PIN messaging. does this number stick with the BB, regardless of activation? so what I am saying is, if I had an unactive BB with a PIN number that number will still remain the same regardless of activation.

Correct. Just like the VIN of a car, it doesn't change.

so if i upgrade later on to a new blackberry would i have to get a new pin?

Yes.
I would recommend doing a search of your address book to find your fellow blackberry users, and sending them a message informing them of your new PIN.

That would suk if someone else got your bb used and kept receiving pin messages from all of your friends

If someone bought a used Blackberry, yes, that would be the case.
I do think however that if you were to receive a refurbished model under warranty repair, it has a new PIN. I had 3 replacements and never had a "strange PIN" come in.
I would also never recommend buying a used Blackberry...just because the warranty is so crucial!
