Ok...I said I would stay away from the forums for a week but was really bored in class today. So I saw 2.1 leaked. Well, I'm no fool, I DL'd that real quick and tonight I installed. It's great.
Pros:
Real fast, responsive (without tactile vibration), and intuitive. I would say a more enhanced version of 1.5 w/sense.
Anyone who is holding out, go for it. You can downgrade if you don't like it.
Cons:
I don't care what anyone says I like the tactile response with typing. Unfortunately it's VERY laggy with it on. With it off, it's super responsive but I'm still used to my vibration.
No animated wallpaper. Guess that will be in the OTA.
Instructions:
1. DL the zip files
2. put it on your SD card, (not in a folder, just e,f,d,h,i:\)
3. turn off
4. hold power+call button
5. press volume down key to HBOOT
6. press the track ball
7. press the track ball again
8. wait
9. wait
10. 2.1 w/sense BAM!
