Help New user, can't install apps

[ADVWannabe]

I recently got myself a Motorola Droid X and my wife the Samsung Galaxy S. I can install apps on the Motorola until my heart is content but they fail on the Galaxy. It goes through the motions of downloading and then throws an error that the dowload failed. It does not give a reason for the failure. Is this phone modified by Verizon not to allow apps or did I get a bad phone?

I turned off the WiFi connection to my home router and I am now able to install apps. Has anyone else had this problem? I know it can't be my router or internet connection because my laptop and Motorola Droid X work fine.
