The report, which cited people having some knowledge regarding Apple’s plans, mentions that the event in September could witness the release of long-rumoured 4.7-inch iPhone 6, a model which is reportedly done with testing and manufacturing development. The final decision is however yet to be taken.

Earlier, another report claimed that due to production issues, the launch of the alleged larger iPhone 6 variant might be delayed till 2015.

It has been learnt from the sources that Apple is slogging quite hard to complete iOS 8 ahead of the iPhone launch and it plans to release the fifth and final beta for testing on 4th August.

Besides, the report also said that Apple will finish work on the final beta next week, while a golden master of the iOS 8 could be expected to be over in late-August or early-September, which will offer plenty of time for testing as well as installation of new iOS onto iPhone 6.

It needs to be mentioned here that earlier an image appeared on web which purportedly displayed the Apple's much talked about models like iPhone 6, iPad Air 2 and the iPad mini 3 models, which feature an embedded circular home button, similar to the one which is found on the iPhone 5s.
