1.0 out of 5 stars P.O.S., March 15, 2009By anonymous - See all my reviewsThe pearl is one of the, if not the worst, cell phones I have owned in 10 years.Within the first few months:-the trackball was working inconsistently-the red call-end/power button functioned only half the time-the headphone jack stopped working consistently. It takes 10 seconds for the phone to recognize that a headset is plugged it, which sucks when you're in the middle of a call. Sometimes it doesn't work at all.What a P.O.S!The only pro about this phone is that the calendar and contacts sync with my Mac OS.To add insult to injury, T Mobile customer service sucks 8@!!5. They only get good reviews because they sound cheerful on the phone and act like they care. God forbid you experience a real problem--half of them don't know their a55 from their elbow. Tech support takes hours. Literlly! And tech support rarely helps (because of the a55/elbow thing).I thought I hated Cingular/AT&T; customer service until I switched to T Mobile. At least at Cingular they don't put on a compassionate facade then dispense crappy service, they just cut straight to the crappy service.
