iPhone 5S, iPhone Math or iPhone 6

Apple blogs are abuzz with the hottest rumor during these cold winter days.

Apple is working on three new iPhone models that it plans to release during the next 12 months, according to a new report in Yahoo News.

iPhone 5S will be launched in June this year as most of the generations of iPhones was launched every year in June. It would be an upgrade to the current iPhone 5, and is a no-brainer.

A 4.8 inch “iPhone Math” sometime this summer, or at the same time as the 5S. It would compete directly with the larger, and red-hot, Samsung Galaxy S-3 phone.

A newer iPhone, possibly an iPhone 6, at the end of the year. It would come with iOS 7, feature a more powerful quad-core ARM Cortex-A15 processor, hold a 4-inch IPS variant display with a resolution of 1917*1080 pixels, have a better 12-megapixel camera, and likely include a fingerprint sensor for security purposes.
