iOS Tip 109 - Limit Ad Tracking

Limit advertisers tracking your location, data
Safari had a mini-makeover in recent versions of iOS, and now offers even more privacy-related tweaks. One of the more recent settings is blocking ad cookies and trackers.
This one is a little tricky to find (as it's not in the Safari settings). Head to Settings > Privacy > Advertising and enable the Limit Ad Tracking option. From here, make sure you hit the Reset Advertising Identifier option, and then accept any prompts.
