At first I want to say, I can't give you any download links, so don't PM me or post here with requests...
This is 188.8.131.52 OS(BETA) for 8100 Pearl.
If you think it's similar with 184.108.40.206 - you're wrong.
The firts different thing is media player.... well it was looking better in 4.3.1 beta I think, but this one is nice too
We can still play video in Full Screen, and switch to list of songs while playing. There's no Bass boost option, or some king of equalizer here.
New camera layout. If there's a risk of 'blur', we can see a small exclamation mark telling us about it.
Bluetooth audio streaming works great, we can use bluetooth headphones, or simply stream to PC or BT enabled car-audio....
Documents To Go works fine for me, no Excel yet, but Word and Power Point to Go are great. We can simply view and edit our files from SD card. No MS Office 2007 support yet (.docx files), and we can't zoom pictures in viewing mode.
Of course we can still use L theme, and folder addition.
