Leaked pictures apparently showing the new iPhone 5 have been published on an Apple rumours website.
The new handset is longer and has a bigger screen than its predecessor while the speaker grills also appear to have been redesigned.
Other changes include the earphone dock which has been switched to the bottom of the phone and the power connector which is visibly smaller.
The 9TO5 Mac website posted the images this afternoon and featured both the black and white versions of the record-selling smartphone.
The source does specify that the new device could also be available in two additional colours, modestly reminding us that they first revealed that the new iPad would come in white.
Fans of the Apple devices may want to remember that alleged prototype leaks have often been wrong.
Apple are unlikely to launch the iPhone 5 - which many hope will boast a faster processor and a retina display - before the autumn.
The iPhone - introduced in 2007 with the touchscreen template now adopted by its rivals - remains the gold standard in the booming smartphone market.
Apple launched the iPhone 4 in June 2010 in black 16 gigabyte and 32 gigabyte versions, and added white ones in April.
The company typically refreshes its iPhone lineup during its developer event in June, but delayed the new model this year.
Apple sold 20.34 million iPhones in the third quarter ending June 25, which analysts say helped it vault past Nokia and Samsung Electronics to become the world's biggest smartphone maker.
Some analysts are expecting another version of the iPhone 4 to be launched along with the next model.
