Ever wish you could edit the contents of your iPhone's clipboard before you paste? ClipboardEdit makes that possible by sticking a tiny text field inside of Notification Center. From there you can edit any copied text before you paste it.
If you're wondering why you'd want to do this, the answer lies in how you use copy and paste on your iDevice. If you just copy once and paste once, it's not a particularly helpful utility. If you copy once and paste a few times (or more), this hack will prevent you from re-editing the text you paste each and every wasted time. If you copy once and paste often, you should pick up ClipboardEdit for free in Cydia. Just be sure to enable it in the Notifications section of your device's Settings app after you install so it actually shows up.
