On July 10, 2013, the US Patent & Trademark Office published Apple's latest trademark application for the new "iCloud" logo/icon that's consistent with Apple's new iOS 7 flat design. The new application under number 86003195 was first filed in Jamaica
Apple also filed for the new green Facetime icon last month. Today the company also filed for the same icon in black and white.
The trademark filing likely indicates that this icon is set for iOS 7 and won't change.
