Today I was using my iPhone in the sauna, but it overheated and was no longer functional. I, however, remained functional for another 15 minutes (well, at least functional enough to read People magazine).
Under normal circumstances, though, the iPhone almost never crashes. Not so for me. I crashed into the box doing box jumps today and banged up my shin. (Yeah, the skin is gone. Also note remnants of previous crashes on my knee).
The good news is that I did 23 successful box jumps (24") before the crash and another 36 after the crash. The iPhone did none.
