This problem occurs on my BB also. I have tried to charge in and out of the holster and both ways result in a reboot. However, when I disconnect the charger from the device I have to turn the power back on. I have had this phone for 3 days and this problem only started today. Should I return it to the sprint store. Is there an options setting I can configure? Please help if you have answers. It is very frusterating because I am missing important phone calls, emails and BlackBerry IM messages. Any suggestions???
