First off, I'd like to say I love the work that was put into this ROM and I'm very sure that I'm an isolated issue but when I put PE onto my D1, I start getting FC's and reboots all over the place.
The reboots are whenever I seem to uninstall an app. The app JUST finishes uninstalling and suddenly the ROM hot reboots to the boot screen. I then have to wait about 2 minutes for my phone to finish reloading all the apps that are on the SD card, which is any app that's not a widget or ADW.
Next I seem to get a bunch of FC's. While this does happen in a number of apps, the worst offender is Rhapsody. I can not tell you how annoying it is to be running on a treadmill and having to pull out your phone every few minutes because the app has FC'ed. I have uninstalled the app and reinstalled it to the internal memory but it just keeps FCing. Again, it happens with other apps but this one is the worst.
Again, I love PE and would love to get these issues worked out. Until then, I'm back to CM6.1.2, which is also elite in its own way.
