I noticed that after the update yesterday I am able to open attachments on e-mail. Prior to that I would try to open attachments and would get the mesage that retrieving file and nothing would ever happen. I also had to reset my login for Facebook. I haven't noticed anything else yet. On another note, a coworker just got the HTC with 1.5 Android. He also likes the software but once he saw a few of the features that the 2.0.1 software has he wants an upgreade.
