This post is closed - the original poster has had the question answered by f4780y in the fourth post.
As a side note to anyone reading - please do NOT attempt to remove your jail break by following the method(s) outlined here by by Redhotpoker. As f4780y so accurately stated, removing Cydia does not make your iPad a stock device, it only makes it impossible to access Cydia.
The only way to restore your iPad to the stock iOS is by restoring it with iTunes (or by upgrading to a newer iOS).
P.S. And, since this discussion is about a jail broken iPad, I've taken the liberty of moving your post over to the Hacking section. Thanks for your understanding.
