Infiniboard

Infiniboard is a Cydia tweak that lets you to vertically up or down your springboard and store apps in them. Normally, you could just slide left-to-right or right-to-left on your springboard pages, but with Infiniboard, you can now store more apps in one page by having the ability of scrolling up or down to reveal the apps that you have placed there. The part, "Infini" meant you could put as many apps you want (like 'Infini'ty!), and scroll up and down. The tweak does cost $0.99 via Amazon or PayPal payments in the BigBoss repo in Cydia.
