Hate to bump this after a month, but I'm getting this issue occasionally with the latest release, though It's not quite so much a hard reset, moreso that it just bumps me back to the boot menu.
The first time it did this, I had to replace my userdata.img as Messaging would constantly crash if I didn't, though the past 2 times, if I let it boot into iOS (which it tends to automatically do after the reset), then restart the phone and boot into iDroid, there's no issues. It seems to do it more when the phone is plugged in, as it hasn't crashed yet while unplugged, though I only just installed iDroid tonight.
Everything else seems to be working wonderfully, just imported my iOS contacts through Gmail, texted some people, etc. Once more features are supported, I can't imagine I'll ever have to switch between the two at all.
