Motorola V600 Phone (T-Mobile)
T-Mobile's V600 NOT Quadband.  US 850MHz band disabled.  Buggy and unreliable.
T-Mobile's website describes this phone as tri-band supporting only the 900/180/1900 MHz bands.    Update 10/13/05:  I'm willing to accept a slight margin for error on personal electronics, but poor implementation or quality control on the V600's have soured my taste for Motorola phones altogether. The interface can lag a little and features like the MotoMixer (mixing samples into ringtones/alarmtones) or even the camera don't have to completely polished, but one truth must be absolute: A cell phone must make and receive calls without fail.    I've already replaced 3 of these for crashing and dropped calls. There would be more, but T-Mobile decided to send a V330 the last time.    Don't buy this phone!
