Feeling paranoid and require the use of a personal GPS
tracker? If so, dig this: Germany's Falcom Mambo II is a quad-band GSM worldphone with GPRS that sports a 20-channel GPS receiver for those detailed tracking needs you may be looking for. That bulge you see contains a helix GPS antenna and some features inside the unit include a SiRF Star III GPS chip
(with GPS tracking using up to four satellites), a 3D motion detector, a decently large 1,200 mAH Li-ion battery and a standard mini-USB connection for charging and connection purposes. No pricing or availability is known yet.
