In an interesting news coming from a 9to5Mac report, Apple might introduce a Jet White colour variant for the new iPhone 7 and iPhone 7 Plus. This year, Apple introduced two new colours – Matte Black and Jet Black (limited only to 128GB and 256GB model) after dumping the famous space grey colour from the lineup.
Apple has been introducing new colours every year now after it first introduced the Gold variant with the iPhone 5S followed by Rose Gold with iPhone 6s. 
However, this information is not authentic at all and never before Apple has launched a new colour variant post the actual launch so we would recommend you to hold your excitement just for a bit.
Contrarily, it might come as a surprise after Ming-Chi Kuo, Analyst (KGI Securities), predicted a fall in demand of iPhone 7.
Ming-Chi Kuo further confirmed yesterday that iPhone SE will not see a successor as Apple is not planning to continue the SE (Special Edition) series.
iPhone SE was launched back in March 2016 in an attempt to offer its current top specifications of iPhone 6s in an old famous design of iPhone 5S. iPhone SE is priced much lower than its flagships so Kuo claims that Apple earns a lot less gross margin on the sales of iPhone SE.
Just so you know, iPhone SE is identical to iPhone 5S in terms of design but it borrows the internals from iPhone 6s with its A9 chip, six-core PowerVR GT7600 GPU, 2GB RAM, 12-megapixel primary camera etc. It, however, lacks the same front camera from 6s and instead boasted a 1.2-megapixel camera. It also supports Apple Pay and comes with improved Touch ID. It also doesn’t come with Apple’s 3D Touch technology seen in iPhone 6s.
