In ICS .10 firmware, Gameloft and EA Game's HD games didn't worked in Xpeira Go.
An now I've updated to .54 and woah, I can play almost every HD games. 
This update also improves the wifi stability too. :smileygrin:
Man, I love gaming on this phone now! So far I tried:
NFS: Most Wanted (v1.0.28)
Max Payne
Asphalt 7
Modern Combat 4
GTA Vice City
GTA III
The Amazing Spiderman
The Dark Night Rises
All the games works fine.
Just one suggestion, download the latest one.
Here's NFS:Most Wanted gameplay I've included from my Go. Though I did increased the graphics now, its not in the video. in the video, its the original one, the graphics can be increased too
On my phone, with 6.1.1.B..54 firmware, the wifi problem is also solved completely.... for about 2 hours after firmware upgrade.
After using for about 2 hours, the wifi unstability come back in full force.
Whenever I move away from a wifi access point, the phone's wifi interface will crash, and the only way to recover is by turn off and turn on the phone again.
