Well this is probably coupled with the 'no connectivity' issue to some degree, but when my phone is searching for service, the phone gets very hot. I've noticed this before when during periods of signal searching it seems like the pocket I'm carrying the phone in is getting very hot. I never really made the association until today when I was holding the phone and saw it had no connectivity when I pulled it from my warm pocket and the phone continued to heat up as I held it and it searched for data. It began to cool as it eventually got the data back. I also think the battery life drops precipitously during these periods.
Has anyone else noticed this?
