Good morning! Just woke up after sleeping at 6am just now.
1 - As I've said before, Stereo Bluetooth audio works like a dream! Using Sony DR-BT50, audio gets piped into the headphone, and fades away as phone call comes in. You just need to pair with the iPhone and off you go. Also, during the call or audio while still in Bluetooth Audio mode to your respective listening equipment, the opo-up option is available to repipe the audio between the different available equipments (if you have paired two or more headphones/BT speakers) or pipe it back to the iPhone speakers itself. Hell, it even works with my Sony Rolly! My Rolly now effectively has 16GB worth of songs, and it DANCES to these songs! AWESOME!

2 - MMS setting, I was wrestling with it this morning, until the very last minute. These are the settings that works on mine:-

Sent my ugly mug of a pic to myself, and got the message back shortly after, picture pinned and all, pops up just like how SMS does , even when the screen is locked. Awesome!
3 - Caller ID is fixed! I can finally remove the double entries I had for all my contacts!

4 - All my other apps works beautifully, particularly the ones I use for work. Specifically, the Foreflight app,...but I need to redownload the AOPA airport diagrams and 3 others 20MB+ heavy bundles back into the iPhone after the restoration. No biggie, done in less than 10 minutes. I dont mind losing the games before they make it work for 3.0, but losing my work-related apps are a big no-no!
5 - The "Shake to Shuffle" feature takes getting used to. Not sure about others, but my "shake" requires subtle shake not the violent "shake a kitty to death" kinda shake. A mild flick and it does the Shuffle. Dont know if it is because I have the Mophie Juice Pack on that made it so, but I'm glad that I dont have to like I'm shaking a marimba in public to get the shuffle going!
