Wow, that can be answered in so many ways!

Seriously:

I used vi and created a test file in MyDocs/tmp/. That file survived a power off / on. I can read the file.

However, things like settings for what mode I am in, what email I last read, what calls display in my call log, etc, all revert to as the state was on Jan 25th. Plus, shouldn't df -h show me the mounts and the amount of space they are using?

For example:
Currently my phone is in online mode. If I power cycle, I am asked if I want to leave Offline mode.
Currently my phone has no status lights or icons. Power cycle it and I have a notification that I have new email. That email is from yesterday. Leave it on and messages come through until I poer cycle.
Nothing is being saved to my call logs even though I have made and received several calls. My call log shows the last call to be Jan 24th.
