Unofficial Storm OS Leak

Another day, another BlackBerry OS leak, with the Storm 9500 being in the center of the, er, storm this time round with the leaked copy of OS 4.7.0.151. Bear in mind that this is no official release, so make sure you make all the relevant backups on your Storm 9500 beforehand just in case anything goes awry. For those who have already given it a go, how do you find it so far? Any snags, or is everything running perfectly fine?
