Interesting that you mention this.....

There was a new software patch release by Motorola on Feb 22 to address this issue. I just downloaded it last night and it updated System Software in my Droid X to 4.5.6210. Try going into your phone settings, About Phone, System Updates. If that doesn't work, go to the Motorola internet site and type in keyword "Droid X software". The instructions and details are clearly listed on their website. BTW, I use Verizon. The information is also on the Verizon support page.
