1) I hate the white backgrounds. Why can't we *choose* which background we want on menus??
2) Not sure I like the recently used list
3) I hate the non-segmented wifi and cell reception indicators
4) I think I like the contacts screen better (very much like it being renamed from "people" which was stupid, to "contacts")
5) OMG!!! They FINALLY added the ability to control the brightness while in Auto mode!!! I have wanted that for YEARS. It was totally stupid that before it could be auto, which was ALWAYS too bright, or manual, which was a pain. Now it appears we have a bias setting while in Auto!!!
6) I tested bluetooth dialing a few times, and I think it actually works now, which it almost never does. It is still incredibly annoying (why do I have to say "select 2" and crap?). Time will tell if it is fixed or still flaky.
7) Not sure I like the keyboard yet
8) So far I see no change in tower reception (T-Mobile)
I have had the update for all of an hour so far... it came over the air this afternoon.
