Here's a couple of man-made-object abstracts that I uploaded off the phone not long before it died (let me know if the links don't work again!!). The first was shot using an app called BlackCam that a friend came across, which seems to do a nice job with B+W photos. I used my usual Vignette app for the second one.
Encrypting the phone and its SD card is good for security, but makes life more interesting when it dies
Fortunately my l33t technical skillz allowed me to resurrect the phone a little while later.
