I am starting to get frustrated with this Tbolt. Prior to the update I had very good battery life and no other issues.Since the update i am going threw 2 1/2 batteries in a 10 hr time frame. I also am getting the random reboots and sometimes my dialer wont work. I am going to do a factory reset, is there anything I need to do before I actually do it, like syncing ? and what do I need to do to get all my contacts and apps back after I reboot ?

thanks in advance , Joe
