While its author openly claims the ROM is far from perfect, most Incredible owners would probably be happy to give this new ROM, codenamed Sky Raider, a whirl simply to see what Froyo+Sense feel like on their rare, practically extinct, phones.
While have not yet tested Sky Raider ourselves, the installation should be familiar to most rooted Incredible owners who have flashed a ROM before.
Note: this ROM appears to require a full wipe (system/user data or “factory” reset).
