Space shuttle Atlantis’ STS-135 mission, a flight notable for its lasts, is taking the first iPhone into space to help with experiments aboard the International Space Station.

Two new reports have indicated that Apple's forthcoming iPhone 5 will only be a minor upgrade over its iPhone 4 smartphone.

The two reports both came from The Wall Street Journal. They first indicating that the new iPhone 5's chief changes would be a reduction in the smartphones size.

The second report from the journal jumped ahead to Apple's rumoured next, next smartphone the iPhone 6, speculating that Apple was holding out until then for its next major iPhone upgrade.

Smaller and a wee bit better

The first report from The Wall Street Journal indicated the new iPhone 5 will be a smaller lighter version of the current iPhone 4 equipped with an upgraded 8-megapixel camera.

The journal cited "people familiar with the situation" from the two manufacturers speculated to currently be building the device as its source.

The Wall Street Journal's report went on to claim that the iPhone 6 will be a significant improvement even over its as yet unreleased iPhone 5 predecessor.

The iPhone 6: Aren't we getting a bit ahead of ourselves?

According to the second report from the Wall Street Journal the iPhone 6 -- which will apparently be out as early as 2012 -- is going to be the next major upgrade in the iPhone franchise.

The journal reported that Apple's chief plan is to add a new charging hardware. Tech site CNET U.K. has since speculated that this new tech could mean that Apple is planning to have the iPhone 6 capable of inductive charging.

Inductive charging does away with traditional power leads and cables, instead charging the device wirelessly. The process works by sending power from a charging station to the device using inductive coupling.

The report also hinted at features including an edge-to-edge display and the inclusion of NFC technology -- meaning users would be able to pay for items simply by placing their phone on the card reader.
