Alright, so I’ve had a full day or so to mess w/ 4.0. My initial impressions are pretty great. Few bugs, which are more than expected. But before starting this, I’m going to say, again, if you are not a dev and do not plan on using 4.0 as a development tool, wait until the official release. But here’s a brief run down of my findings so far, and for you developers who have experienced a couple bugs, such as BoxCar and facebook issues that maybe shouldn’t be happening, I’ve included a bit at the bottom showing some workarounds I found…and some that still stump me…
First off, here’s some screenshots of the main UI. Folders will be a welcome addition. I would have liked an expose type feature but after messing with folders, I managed to skim down my app page number from 10 to simply 3, which is more than manageable.
Screenshots…

Inside a folder. Only 12 apps max (for now)

Creating folders severely minimized home screens..
For those of you having issues changing the wallpaper on 4.0, do it through the wallpaper area in settings, not through your photo apps, that seems to be a bug and that solution is currently not working.

You can now choose your own wallpaper for the homescreen.
GameCenter appears to be extremely cool. I haven’t played with it but I’ve thumbed through the settings and some of the features in the SDK. For game developers, this will be a welcome addition. The Plus+ network and others are okay, but having multiple networks is a pain, this should simplify it. (For any devs who have gamecenter set up, add me. Don’t know if you can utilize features yet or it will tabulate but I’m interested in knowing more about GameCenter.)

Alright, some things seem to have some bugs… here is one I have NOT figured out, if anyone knows a workaround… FaceBook (surprise!)… now a lot of people report having this issue in 3.1.3 and even before that… I never had it, so can anyone tell me if they are NOT getting this when trying to upload pictures to facebook in 4.0?? (Also another reason why people trying to install 4.0 that aren’t devs should stay away. Apps can go all crazy on you, as they don’t have compatibility yet.)

Now here is another issue I did find a workaround to. In Boxcar, on 4.0, many devs have reported having issues receiving notifications. Turn OFF all your noticiations, save, turn back on, THEN go to Quiet Time, turn it on (or off – just change it from what it currently is), save, go back in, readjust and save. That fixed mine and I’ve been getting notifications just fine.

Change Quiet Time in 4.0 for Boxcar to fix not receiving notifications.
As far as other features, I’m still digging into the SDK and the software itself, character count in text seems to be working now… A lot of people are saying it’s not, but I don’t think it kicks in until you have over 50 chars…

Character count in 4.0, little buggy right now, but seems to work
I didn’t start playing with 4.0 until this morning – as I didn’t get around to installing it until about 2am last night. Most of my time has been spent digging into APIs and such. But these are my initial impressions and such. I think 4.0 is definitely a step in the right direction.
