After installing all of my apps, I powered down my phone. After it powered back up, several of my apps were missing. I had to re-install them. The funny thing is that I did not have to re-enter usernames and passwords - all of the data was there. I restored my apps with MyBackUp and powered the phone down. When I powered it back up - the same apps appeared to be missing. The icons were these blue icons w/ a generic gear in the middle, but what I clicked them, they were still there technically. Not sure what to do. Don't want to have to continuously re-install apps.
