I am running 0.3g - and have no issues thusfar, it's great!
Only thing is when I am in homebrew it always prompts to update - which I believe installs another IOS? Perhaps not but something in the process threw up a red flag for me.
While I'd like to have the latest homebrew installed I don't...
sometimes to the point of thanking me for my quick actions etc against spam and other stuff, but yea...its either they come to respect me or outright hate me
