I have a 32gb Touch that worked great until I upgraded the firmware to 2.2. Upon doing so, I am only able to unlock using the slider, then the touch is "frozen". Occasionally, I can get, perhaps, one level into the settings before everything is frozen, but that is it. Beyond that, I have to use the power button to return to the unlock screen, but once I slide to unlock, I have the same result. I have been able to revert to 2.0 and all is well; however, 2.2 or 2.21 leaves me without any functionality. I wouldn't care so much, but a lot of apps now require 2.2. Thanks in advance for any help you can provide.
