How long does a SMS message "session" last? On my old blackberry, messages would just keep rolling off, you could scroll back about a week or so, but I have yet to figure out how to cut down on how long the messages stick around on the Incredible. I activated my new phone around 2 weeks ago, and a chat thread with one person has reached over 850 texts, so now it takes forever to open! Is there a way to set how long the messages are saved? Kinda tough to describe, hope someone understands wth I'm talking about!
