Brightness isn't the problem. It's the contrast. The colors are darker because it has higher contrast. Plus, there's scanlines.
I think I've heard some reports about this on the newer 2Gs. Mine came with 2.2 so it was brand spanking new and was probably boxed only a month ago.
BTW, did you get Asphalt 4?
Bump:
At least it charges quickly.
OT: Who has Super Monkey Ball...legally?
Mine came with 2.0... and my sister bought Super Monkey Ball on her touch, I haven't tried it out yet.
EDIT:
Can someone help me? Something seems wrong with my balances, there different on my itunes on my pc and my touch, i feel like buying tons using my pc, lol:
