New options in Settings
A)In Sound settings, there are several new options. Under Incoming Calls, there is 1)a Pocket Mode(increase ring while in pocket or bag), and 2)Flip for Speaker(Turn over your phone to activate the speaker during calls).
Under Feedback, there is Screen lock sounds(play sounds when locking and unlocking the screen)
B)in Applications Settings there new options. There is 1)Development(set options for applications development), 2) Storage use(view storage used by applications, and 3)Fast Boost(turn off to use some Market apps[already Checked])
When you are in the Application Settings, hit Manage applications, go under On SD card, check out all the apps that are on your card, and the ones that are unchecked to can go on the card(THIS IS SOOOOOO COOL)
Under the same settings go under Running, press any app you don't want to run and it will tell you "Stopping it may cause the app to fail." They also tells you that app(example Lookout has 1 process and 3 services.
This is what I have noticed so far, will tell more later
