According to the Handspring website the 600 will become available depending on what carrier you have. I will be upgrading to a 600 and it looks like they will selling units tied to a carrier (hence the carrier pull down menu). Whats up with that? Does this mean that they will not be selling an unbranded unlocked GSM version? I will be pissed if I order mine and it has a pink T_Mobile logo stamped across it.
