Veracode found out that one of the most Android apps Pandora Radio sending quite intimate details of users to Pandora’s and advertisers' servers. As a publisher I know that certain details must be sent to ad networks about user/visitor but I believe it must be voluntary opt-in feature so that user of the app can decide freely.

According to source below, minimum ad budged for Appl'es iAd Platform is $1.000.000 in the U.S and £600.000 in the U.K. 

So unless you are a very big company and wan't to target Apple products only prices are way to high.

A rough advert slipped in to Admob's publisher network costed money to quite few people who use iPhone application called Talking Tom Cat.

Application designed for kids was using Admob adverts to support free version and some adverts was designed to trick users/children to click and dial premium rate numbers.

Admob said: "Click-to-call ads with premium numbers are classified as age-appropriate and normally would not appear in apps for children. We will work with the app developer to block these ads if we discover they are showing."
