I have had the Droid X for two days and it has locked up several times. I've had to shut if off and leave it shut off for quite a while before it begins working again. Last night after fulling charging the phone, I began using it to only have it lock up again. Tried to pull the battery, but could not get the back of the phone off to access the battery. The phone appeared to cycle on and off. This morning the phone was completely dead. Plug it in and it turned on again. I'm headed to a Verizon store this morning. I can't have an unreliable phone.
