Just wanted to put this out there for folks who may be experiencing stutters, lag or other issues...
You may want to try clearing the cache partition occasionally and especially when you upgrade to the new Beta builds as they drop. It's not a magic bullet and may not even work but it is something that will help keep you running more smoothly.
I do this any time my phone starts to *seem* slow or laggy. I also take the extra time to repair apps after clearing the cache...again, may not really fix the specific issues you are experiencing but it's something to try.
