I recently put android onto my phone, but some things have broken in my upgrade path:
1) Thumbnails no longer display in gallery, which is a pain when I'm trying to look at photos etc
2) I've noticed from version to version the display has looked a little blurry in certain releases. This latest release (the one that fixes the GPU) is looking a little blurry, but no biggy.
In the latest release I didn't upgrade, I replaced all the relevant files from the zip into the storage card. Does HaReT or android create any other files that I can remove to get a clean install?
