In early 2010, the European Commission launched an investigation into Apple’s policy of insisting on a “country of purchase” rule under which warranty repair services for iPhone applications were only available in the country where the iPhone was purchased. In a parallel investigation the Commission also inquired into Apple’s decision in April 2010, to restrict the terms and conditions of licence agreements with independent developers of applications for its iPhone operating system which limited them to using Apple’s own programming tools and approved languages to the detriment of third parties. In response to the concerns raised, Apple announced that it would no longer enforce the “country of purchase” rule and has appointed independent authorised service providers where Apple does not carry out repairs itself. Apple has also removed restrictions on the development tools used for iPhone applications, allowing developers the flexibility of using third-party layers so that the applications could run on competing platforms.
