Can I block ads on an iPad? I am about to buy an iPad, and was using a friend's device recently.  I noticed all these multi-colour intrusive square things I'm completely unused to seeing because I've been using Adblock Plus for years now.

What are my options?
No need for a jailbroken iPad, iCab can block ads http://www.icab.de/mobile.html
And it is a great browser.
