Tinah, there is a Factory Data Reset in Settings someplace near the bottom of the page (sorry -- running Ermine now ;/). It is in one of the eDGe listings, not anything obvious.
Tap Settings (either the app icon or from the menu button), then tap on the second to last heading (or the last, or third to last) and look for it there.
Let us know if you find it.
And tell why you are giving up your eDGe so soon!!
