I upgraded with a clean wipe. What I noticed when I long-press the power/sleep button, the menus do not match the icons they are associated with. Anyone seen this happen?
There may be problems with your recovery. I flashed over to an alternate recovery .99b and re-flashed it back to Rom manager's 2.5.01 version. I also had problems with the reboot after trying to download an app from market. I found out that I had to do a full wipe before installing MIUI. Hope...
