I have owned this unlocked GSM 600 phone for 3 agonizing years. Not sure whether to lynch the engineers, techs or marketers!!! Lots of potential and promises and absolutely horrible customer care. Treo and PalmOne really sucks and is pushing otherwise dedicated customers to other smart phones. Blackberry does less but more reliably. So long you silver piece of _____, I am tired of dropped calls, shut offs and resets. JGK
