Krazit, Tom.  "Google restores tethering app for Android users outside U.S."  CNET.com.  April 2, 2009. 

This article from technology web site CNET presents a news story about Google's pulling an application from its app market due to a violation of Tmobiles terms of service.  The app, which was a tethering app - an app that can be used by Mac and PC users to gain access to the internet through their phones, was banned by Tmobile and was subsequently removed from all app markets by Google.  The problem was that the terms of service violation only applied within the United States and with phones that were locked.  Google quickly remedied its universal takedown by putting the app back up on app markets outside the U.S. and by restoring access for unlocked phones. 

The news story is not so much notable for the tethering app in particular, but rather because it presents an instance in which Google's open access software comes into direct conflict with the network operator on which it runs.  The article notes how "It appears Google's commitment to making Android a completely open operating system will be tested by the reality of how wireless carriers have traditionally controlled the applications that run on their network."  This is an important point because it highlights an inherent contradiction in the ways open source software and mobile network operators function.  This contradiction will likely prove to be one of Google's primary challenges in establishing Android as a widely used operating system in the mobile market.
