Just flashed to r04. First thoughts:

• like the new lockscreen with the Manila-style clock, hate the wallpaper, and the lack of ability to change that wallpaper

• Went back to old style Bing, good move

• Like in r03, could really live without the TouchResponse application

• Still using ArkSwitch huh? still freezes the shit out of my phone....

• Still have to configure the data connection and MMS server settings

will report back as I use it more.
