I tested the new version of GMM on my Bold last night - works like a charm! The download screen noted my BlackBerry Model number and offered up the lastest build of GMM to me.

Interestingly enough the "Google Mobile Updater" didn't offer the new version to me.

NOTE, however, that Google has a disclaimer on their site that basically says "This is a very data intensive application. We strongly suggest you have an unlimited data plan". (Not the case with Rogers, sadly, but perhaps the rest of the civilised world could use it?)
