I'd like to stop using IM on my blackberry (corporate issue).
But I want to communicate with someone with a cell phone who does not have web access, just IM.
This person is on AT&T, as am I.
Can I email to their phone number @ att.net (or some other tail), and if they "IM" back will it be converted to an email on the AT&T gateway side, or is this something I need to setup myself?
