Some of the most popular apps written for Google's Android phones do not tell users what data they are gathering, says a study by US researchers.
Half of 30 applications studied share location information and unique identifiers with advertisers. Information about the data gathering was collected using software developed by the team. App creators should provide more information what will be done with harvested data, they say.

Meh. Any proof that the Iphone does not do this? Already seen the reports on hidden charges in apps (although some require a password for payments, it does save the pass automatically, so defeats the point).
In its simplest form Apple knows where every iPhone is located by the use of geographical data collection from the phones internal GPS.

According to the article one is allowed to choose whether any information is exchanged and from my experience this seems to be the case.
Not really surprised as Google's main business is selling advertising
