Dude. You're screwed. This isn't the "stable" Hong Kong version. It's an old beta version of PR1.2 that got leaked somehow and now a bunch of fools and impatient folks have it running on their N900's. As has already been stated, you're going to have to live with it until the normal version is released unless you don't care about your cellphone. Going back to 1.1.1 will disable your cellphone. So you're pretty much stuck with a crappy unstable version of PR1.2. Hope it was worth it.
