This upgrade is an improvement from 1.0, as my Treo crashed (hard crashes) a couple of times. With version 1.1, my treo hasn't crashed once. I just wish they didn't remove the call history button. I would also like to see the ability to send sms from the phone book. An sms button beside the dial button would be nice. Call tracking (minutes) and data (kb) tracking would also be nice. Although, the Treo 270 is pretty much perfect.
