My overall memory appears to be a bit lower (123ish vs. 124ish) but that's no big deal. Haven't really used it enough to notice any memory leaks, will keep an eye on it today. Only items I have listed as "Third Party" under apps is VZW Visual Voice Mail and VZ Navigator.
At my ITs insistance I re-loaded this last night. Memory was stable until I utilized MLB At Bat 2010. Then it started leaking like a drunk teen. 10 megs overnight. It appears that this OS and 2010 don't mix all that well. RSA Secure Id is still broken as well, and my firm has requested no one else update because of this. Fortunately going back to .428 - maybe .517. I'll decide in a day or 2.
i have been running this since it was available OTA no memory leaks at all. I did 3 battery pulls in a row as recomended by a friend of mine checked my memory and it is holding strong with no leak.
