NeoWin found some rumors about Apple's iPhone 5 at a Chinese website. According to the source, the new device will feature a new antenna design as well as an aluminium rear. The processor is expected to be the same as in the iPad 2, the Cortex A9-based A5 multi-core chip.
After facing a lot of issues with the scratched iPhone 4's, Apple are, according to a Chinese source, planning to use aluminium for the rear part of the iPhone 5; this move would take the iPhone back to its roots and closer to the iPod Touch 4G. The decision to change to a metal base instead of glass will make the existing complaints of the phone being heavy and easy to damage a thing of the past, however this might change when the phone is released to the masses.
The current side mounted antennas on the iPhone 4 have also been abandoned, instead there will be a single point on the rear of the phone underneath the Apple logo. The idea behind this is to make WiFi and mobile signal much easier to penetrate the phone, which also takes care of the complaints about reception.
When the iPhone 5 will be released is unknown, but during the WWDC in June or July is a likely guess.
