Currently if you have a stock Phoenix you probably have Froyo 2.2.1 installed on your phone. Thanks to AT&T you can't load apps other than from the market. So you will need to do one of two things to get you phoenix to accept the installation of third party aps.
Option 1 (update your phone)
Go to your settings menu, then click on "About Phone" [all the way at the bottom]. Then click on the "Software Update", then "Update Now". It should check for an update [make sure you have a good internet connection] and if you aren't already upgraded is should install Froyo 2.2.2 which among other things allows for the loading of third party apps. Please be aware if you have rooted your phone some people have run into issues with this update in which case you can go to option 2
Option 2 (dial pad)
Go to your dialer, type "3845#*506#" (you may have to press send). This will unlock the third party updates.
After you have this unlocked/updated you will need to as stated by lunatic59 and goto menu>settings>applications and then click unkown sources.
