The rumour mill has kicked into gear once more, after word from a Foxconn employee indicates a summer launch for the next-generation iPhone is likely.

The upcoming Apple smartphone is apparently all set for production, and it could be released during the summer months.

This newest iPhone 5 rumour comes from the guys over at 9to5Mac’s “reliable source at Foxconn in China” who has revealed that there are several sample devices on the scene at the moment.

These next-gen iPhones share some common features, including a 4+inch display, a design that won’t be teardrop-shaped but will be different to the iPhone 4 and 4S models. Each version differs a little and it is unknown which one will end up being the real iPhone 5 – at least one of the iPhones in production is said to have a display made by LG.
