For the past day and a half my X has been running way slow. It lags big time when trying to open the text messaging screen. If it does finally open it'll crash most of the time when trying to resolve the phone numbers to names. I've done a reboot, a battery pull, I've killed tasks using Advanced Task Killer (I don't usually use it). What's the next step? Factory reset? I'm coming from the BlackBerry world where I would just download the latest OS and reload. What's the process here? Thanks!
