BEWARE!  I had the same issues with my Motorola Droid Razr X giving messages that contacts had stopped every time I had an incoming call and I had to press OK.  When this problem worsened quickly in one day, the phone is now in a continual loop at the droid red eye start up.  I have reset the battery, cleared the cashe, reset to factory settings (getting all info from verizon and motorola forum searches) to still be where I am with the start up.  After over 1 hr. on the phone with Motorola, a visit to my local verizon store, tech chat with verizon & motorola...    I am expected to purchase another phone.  It won't be a Motorola....they do not continue to update tech issues with a phone that is over a year old.  I am about to use whatever I can online to reconfigure my device because it is of no use at this point.  If anyone has a link that is best to walk me through this process, please post!:'(
