Choose the "download link" afterwards go to ifile if you have it installed. var/mobile/media/download. Locate that download, click on it. It will bring up a box with several options. Click on "web viewer". Your download link will appear! Cheers
In case anyone was stuck like me...I installed it using my pc. Download it off google code, right click on the ipa and choose "open with", choose iTunes. It will appear in your app library and sync to your iPad the next time you use it. You must have appsync installed on your iPad. With retinapad going it's a beautiful little program!
