Is there an SMS-based Instant Messaging client that supports Google Talk (jabber)? Just as the title says, I'm looking for an SMS-based Instant Messagiing client that supports Jabber (Google Talk more specifically). I recently jumped onto Sprint's SERO plan and got unlimited data and unlimited SMS in my plan. All the IM clients I've found require a constant internet connection and I would rather not have that as that drains my battery. Is there such a program out there? I've read that there are AIM / ICQ / MSN / Yahoo clients that do this, but none for google talk. Thanks!
