BGR is reporting that the next-generation iPhone is in the engineering testing phase of development and has not yet been put into production. Specifically, the device is in the EVT3 or third revision f the engineering test stage, which is a step behind the design verification test stage.
The report also chimes in on hardware details, claiming that the new iPhone will have LTE built in, 1GB of RAM, and the inclusion of near field communication (NFC) technology to further bolster the Passbook wallet feature in iOS 6.
To me, none of this sounds unreasonable, with the possible exception of NFC technology. As outlined before, it seems that Apple is waiting for retailers to buildout the infrastructure first before they include the technology in their iOS devices. As we move forward, and with the inclusion of the technology in the current-generation iPad, it seems that LTE in the new iPhone is a safe bet. A full gigabyte of RAM is just icing on the cake.
