well this is rather self explanatory, which one is better? I've read up on both of them and there about equal. i was hoping i could just get some more user opinions. i want voice calling, and that about the only want... but i would like to know how they work more or less. like how annoying is the hold feature when someone is calling on the m620. or maybe how useful is the wee display one the m610? also the duribalty of them. so basicall what you guys liked about and didnt like about the 2! as you can see this is my first post so if im doing anything wrong please correct me. Thanks!
