Hi, I just picked up the Motorola Droid, and I'm loving it I'm trying to find the best free alternative to SMS (because it's ridiculous that after paying $30/mo for 3G access, I have to pay more to move 100-character messages around on the same network...). Ideal would be something like BlackBerry Messenger. So far, I've been using gTalk with my status set to invisible, and that seems to be a pretty good alternative. When I initiate a gTalk conversation with an invisible status, the conversation usually remains short - like an SMS conversation. One downside is that people never initiate conversations on gTalk with me while I'm set to invisible. Does anyone have any suggestions for a better alternative?
