Thus far I've noticed no dramatic differences other than the unlock screen, but I haven't used the phone extensively. I have a 415 area code, and my number ends in 01.
Hey Patti
I'm curious, how do you now unlock the phone?
I really liked the half circle used to unlock or mute the phone, used in OS 2.0. It was easy to drag it to the left to silence/unmute the phone, or drag it to the right to simply unlock it!
Now I see two tabs... do you simply drag them to the edge of the phone?
(Wonder what the reason for this change was.... were people actually confused about how to unlock or silence their phones???)
