I have had it running now for a couple weeks and do not notice any problems. The only issue I am having (started a thread about this) is that my new message LED notification light will not turn off when I have a missed call and view it and even delete it. I have to power on/off to get the light to stop blinking. For now I have disabled it in my profile. My pearl never had this issue so I don't know if it is a problem with the 4.5 OS or not. Here is a link to the file:
