I have tested this over the last two weeks and I am convinced 4G will not connect when I turn my phone on with fast boot enabled. I have played with the setting and at best 4G will connect 30% of the time when coming out of hibernation. I always get 1X, so I always have to do a battery pull to get 4G back. If I disable Fast Boot 4G comes up 99% of the time. Anyone else experience this?
