I am using version 1 and it's been running well. I also installed the higher frame rate update (normal volted eclair) from
http://forum.xda-developers.com/showthread.php?t=711964 and now i'm getting 44fps on fps2d.
If anyone does this and their wifi breaks like mine did, install the wifi 4g update for stock/custom kernal on that same link to fix it.
I used Rom Manager to install both BTW.
