ModMyi recently created an online directory that lets you browse Cydia apps directly from your computer. It’s something I had thought about doing for a long time, but didn’t have the technical skills or finances to put it in place.
Cydia apps listings show basic information about each application as well as a screenshot.
I find this tool much more convenient to use than your iPhone/iPod Touch when simply browsing apps. Note that you won’t be able to download any app from the site.
