Pastebot is a powerful clipboard manager that stores text & images copied from your iPhone/iPod touch. Organize, apply filters to, and copy clippings to be pasted or sent to other apps.

There’s also Pastebot Sync that lets you sync the iPhone/iPod touch with a Mac. Pastebot v1.2 “lets you connect multiple devices to your Mac at the same time.” I consider Pastebot and Pastebot Sync must-haves.
