Apple on Tuesday sent official invitations to a September 10 event at which it is expected to unveil the latest version of the iPhone, possibly in colours other than its trademark black and white. “This should brighten everyone’s day,” the typically cryptic invitation read, under a graphic depicting pastel-coloured circles surrounding a stark white Apple logo. The company, which is making a focused effort to win over consumers in Asia where rivals Samsung Electronics Co Ltd and other Android manufacturers dominate, said in the invitation it will host a breakfast and presentation at its Cupertino, California headquarters. The company did not specify as to what the presentation will be about. But supply chain sources told Reuters in June that Apple is expected to launch two new models this year.
