It has been an on-and-off situation for rumours regarding the upcoming iPhone 7. Whether Apple's new flagship will feature a 3.5mm headphone jack or not, has created quite a buzz in the tech world. After numerous rumours suggesting that Apple will finally let go of the standard headphone jack, new rumours are hinting otherwise.

According to Engadget, via a Chinese repair shop Rock Fix on Weibo, new images of the alleged iPhone 7 parts have been leaked online hinting at the possible specifications. One image shows a 4.7-inch iPhone 7's Lightning cable assembly, which indicates the 3.5mm headphone jack is intact. While it seemed too odd to imagine an iPhone without the headphone jack, LeEco's introduction of jack-less Le Max 2 and Le 2 smartphones makes the design more realistic. Apple could use its Lightning port to connect its headphones, like LeEco does with USB Type-C port.

Other photos leaked by the Chinese source show dual-SIM trays, which will be the first for Apple in the iPhone history, a SanDisk memory chip offering up to 256GB storage option and a dual-lens camera for the 5.5-inch iPhone 7 variant. The tipster also told Engadget that Apple won't get rid of the antenna bands at the back of the phone, but said there will be some changes to their design.

A slight change in the iPhone 7's design has been reported in the past. The antenna bands are likely to be moved along the top and bottom panels, keeping the rear panel plain. Also, the introduction of the 256GB storage option adds more validity to the previous rumours about Apple's plans to ditch the 16GB variant and offer options of 32GB, 128GB and 256GB for its upcoming iPhones.

Other leak suggested that Apple would introduce a new deep blue colour for its iPhone 7 and dump the current space grey option. The Cupertino-based tech titan is also expected to introduce wireless charging support, dust and water-proof design, upgraded camera, speakers, chipset and battery into the iPhone 7 series.

However, nothing will be official until Apple launches the new iPhone series, which is expected to happen in September this year.
