How to get BlackBerry App World back on my BlackBerry?!?

-I went on blackberry app world and it said it needed an update so i updated it, and then it needed to reboot so my blackberry curve rebooted and when it came back on blackberry app world was gone! how do i get it back and is there any other way than connecting it to the computer because i have lost the USB lead?this is a common problem. type in google search on your phone "blackberry apps world download" and you can get it back that way.
