BrewMath and the 3.0 SDK

It's been pointed out to me that BrewMath crashes immediately on launch on devices with the 3.0 beta SDK installed. As the beta is really a developer only release (and end users shouldn't really be installing it) I don't currently support using the 3.0 SDK (this means you're on your own if you do). I will of course try to ensure that BrewMath runs fine on the new SDK when it is eventually publicly released by Apple.
