And people wonder why they should jailbreak...
If you're into multimedia, XBMC-ios. It's weather, pictures, music, videos, and more in one place. And if you have a home network you can link to your media files on your computer or NAS from within it.
Scrollingboard - endless icons in the dock, endless icons and scrolling in folders, and more. Probably the poor cousin of Springtomize.
iFile - the Swiss army knife of file apps. It does tons of things but what I find most helpful are:
1. You can connect your ipad to your computer with the built-in server and transfer files by wifi.
2. With the camera connector kit you can view all the pictures on your SD card full-screen, which you can't do otherwise. And you can add pictures to the Camera Roll by pressing a button. You can also print and delete pictures from within.
Some people report success with reading files from an attached usb flash drive using the other connector in the kit, but it has not worked for me.
Last, the iDO-notepad, a note-taking app with many settings for notes. Its chief value to me is its built-in print function. I can print through my computer to the printer with AirPrint for windows. But it won't work for printing a selection. So I copy the selection to this notepad and print from there. You can't print from the notes app that comes with the ipad.
Better jailbreak before Mickey330 empties out the repositories. ;-D
