I ran the update and have been playing with it for almost 6 hours now. Personally, I think this ROM runs a little slower than the previous ROM. I reflashed the phone twice just to make sure nothing was messed up during the first flash. still slow.
i also notice problems when typing text messages/email. the phone just cant keep up with my speedy fingers. if i hit a letter to fast it displays the number instead, like if you held down a button. its very annoying.
push email works great too and some new awesome features were added. they are as follows:
- t9 now keeps the word you were spelling when you input a word. looks like someone read the fight night article

- the camera works like it does on the SDA, saves pictures to folders with the date. once again it looks like someone read fight night

- file manager has magnifying glasses in place of the folder icons when in "list view" mode... im confused as to why
i guess ill give it a week or two before i really start to trash/praise it
EDIT: just restarted the phone, file manager icons are fixed but icons on the homescreen are wrong (wireless homescreen). flicking on the would be file manager icon takes me to the settings menu. the call history icon takes me to contacts.
