We've all heard of cell phones spontaneously exploding because of bad batteries or some kind of short circuit. One of PPCGeeks users, kidmet, had a spare Touch Pro battery in the back pocket of his pants. He walked into his home earlier in the week to be greeted with a burning smell in the air. He later went on to do some laundry to find a huge hole with burn marks in the pocket of his pants. The battery in question must have expanded and burned through it. No word yet as to whether or not the battery was a battery from HTC or an after market one. Luckily the explosion didn't cost him more than buying a new pair of jeans.
