My Eris is having a problem deleting message threads in my Messages or single messages for that matter. I'll try to delete the thread and it'll sit in 'working' mode until i reboot the phone. Normally, it takes a solid minute to delete a thread of only 20-40 messages. i've been trying to restart the thread between my wife's phone and mine (3026 messages) and it just stays in 'working on it' mode. Can i manually delete the threads using my computer and the data cable?
