So I rooted my original Moto Droid back 6 mos ago or so. Flashed the Ultimate Droid 1.0 Rom because it seemed like the newest UD Rom still had some bugs at the time. I haven't theme'd it. Anyhow, just wondering....if I use the settings without installing any new kernal, it's set for minimum speed of 250, and max of 650. How far north of 650 can I safely set the overclock without ending up with Droid Au Jus. I've thought about upgrading to a newer version, but not sure of the difficulty of backing up apps, emails, sms and mms. When I flashed the UD Rom I lost all my sms, mms, call logs and emails. pissed me off.
