It looks like I found 2 bugs with the 2.1 upgrade for the CLIQ. 1. The signal isn't as strong as 1.5. I have 2.1 and my brother had 1.5. We were in the same location and he had reception and I did not. 2. I think this other one is with the T-Mobile "My Account" app. I keep my screen brightness on the lowest setting. When the My Account low battery indicator comes up the screen brightens to about 33%. Has anybody else seen this?
