We didn't believe it at first but the rumours sure do seem to be stacking up. AllThingsD reports that on September 10th Apple will unveil the gold colour iPhone at an event that will be more champagne than gold. Multiple sources have also told MG Siegler at TechCrunch and Rene Ritchie at iMore about this mysterious gold iPhone. The front will apparently remain white, however the back will have some sort of gold/champagne colour.
Many rumours have also said that the Home button of the next iPhone will feature a fingerprint scanner that may integrate with security settings in iOS. However some sources claim that it won't be suitable for things such as payments.
