Here is a small issue that I ran into.

After upgrading my HTC Evo Shift to Gingerbread I discovered that I could no longer connect my phone to my computer and get to the SD card.  I tried installing the latest HTC Sync software, but that didn’t seem to fix the problem.  I read a few other blogs and then tried getting the latest Android SDK.  After installing that I’m back up and running.  Pretty simple, but pretty annoying.
