A new application under the name of HWPlanner has been released on the iPod Touch/iPhone on Cydia. This application is a very high-tec homework planner.
In this app, you create all the subject that you have and then write in the assignments you have to do for each class. You write in the date due and set and there you have it, all your assignments on your iPhone/iPod Touch. It saves each assignment as a calander event as well meaning you can set an alarm to when you want to be alerted.
You can get it off the BigBoss repo (CLICK ME)
