HP’s Touchstone wireless charging technology as shown with the Pre

The Wall Street Journal follows up on their earlier report about the iPhone 5, once again calling for a thinner and lighter device with an 8 megapixel camera – but with a design akin to the iPhone 4. Tonight’s new report claims that Apple is already at working on a major iPhone revamp for the product’s sixth iteration. The phone, which will launch sometime in 2012, is said to include a “new way of charging the phone.”

This “new way of charging” jogs our memory of a report from This is my next, who claimed that Apple is already at work on complete iPhone revamp. That report pegged a thinner device with a 3.7 inch Retina Display, a gesture-based home button, and “cable-free juicing.” Perhaps this new way of charging is HP webOS-esque cable-free charging. Perhaps this also means that the other innovations discussed by This is my next will appear in the sixth-generation iPhone.

In addition, the WSJ is reiterating earlier claims by many and says that Apple is still working on a lower-priced iPhone with an edge-to-edge display. On a final note, contradicting Bloomberg’s claim that the iPhone 5 was delayed until September because iOS 5 was not ready, the new WSJ report says that the iPhone 5 is launching in late September because the hardware was simply not ready for a summer launch.

The fifth-generation iPhone is also expected to feature the dual-core A5 processor found in the iPad 2 and a new Qualcomm-built cellular chip that can connect to both GSM and CDMA networks across the globe.
