In OS X I can use extensions in most browsers to block ads. This offers an distraction free browsing experience.
For example: In Safari, Chrome and Firefox I can use Adblock or Adblock Plus. Both extensions use filter lists which you can find here. You can also manually add filters and add sites on which you accept to see ads (e.g. apple.stackexchange.com).
What options exists for ad free web browsing in iOS?

Use Privoxy as an ad-stripping proxy server on a Linux box such as the inexpensive Raspberry Pi featured in this article: http://kimondo.co.uk/raspberry-pi-as-an-adblock-server-for-ipad-iphone-android-and-anything-else-on-your-network/
I have tried this and it works well. (Obviously no jailbreaking is required for this solution).
