I like this release. I put it on yesterday and it does seem snappier than the official release.

One thing I found in the browser is that it zooms way better than the previous version. The redraw of the screen happens more quickly.

You can also make the browser go to page be "Thumbnail View", which, like a Droid or Chrome or other browsers, gives you a little thumbnail of the page instead of the list. Cool if you like that.

I had text messages set to switch to MMS if I typed too long. I don't know if it was in the previous version, but I now have it set to stay in SMS if text only. It then will pack together up to 7 160 character messages for you. If it was there in the past, I missed it. Ooops. For me, this is way better this way because our corporate plan has unlimited SMS for Blackberries, but MMS aren't included.
