I’ve been playing with location-based services today. GSM-based localization told me unmistakably that my cellphone is closer to belong to the local bulky waste dump than to my work place. Then the hauptstadtblog comes along and reports about Berlin emergency services using cellphone localization to ease their work. I know now where they will be searching for my body.

Still, attaching a cheap used cell phone with a good standby time and a powerful battery to your belongings may be the cheaper alternative to buying a 450€ professional GSM device. Especially when you don’t need it.
