I want to know the answer to the following question:
What did the MoU make the manufacturers agree to do?
All the background I'm provided with is that "In June 2009, many of the world's largest mobile phone manufacturers signed an EC-sponsored Memorandum of Understanding (MoU), agreeing to make most data-enabled mobile phones marketed in the European Union compatible with a common External Power Supply (EPS).". Is that enough to answer the question?
Answer: yes
