I found a proc buried deep in /sys/ that controlled orientation when you echoed the right value into it. I forgot exactly where. I should have documented my research while poking around the /sys/ tree.
Great... I just did a recursive grep in my /sys/ folder for "orient". After it reported a bunch of "Permission denied" messages it locked up. Even the power button does not work.
I had to do the long reset. It is restarting now...
BTW, I discovered when doing timing tests with
time cp file.xxx /dev/null
that it DELETES the /dev/null device and creates a /dev/nul FILE, resulting in a "device full error". I was comparing large file copy times against large file decompression times, while porting my old memory compression code I use in my windows apps for much faster speed. It is MUCH faster to copy compressed data from the dictionary window in cache than to copy new data from RAM.
Anyway, I was wondering if renaming devices could be useful for MITM code (after a jailbreak) to intercept OTA updates, for example...
@yifanlu: Did you see this? It is what I was referring to as the "other" exploit:
[... secret URL ...]
I was thinking along the lines of an iPod style tethered jailbreak to encapsulate, automate, and hide all the client-server communications cruft behind a pretty GUI interface. Cross-platform for Windows, Mac and Linux (using an SDL framework I already have working), of course.
