It seems a cheaper 8GB version of the iPhone 4 has entered its manufacturing stages. According to two unknown sources for Reuters, Asian suppliers are assembling the iPhone 4 with a lower memory capacity and the new 8GB flash drive is being manufactured by an undisclosed Korean company. It could be Samsung Electronics although there's no official confirmation on this. The new lower-capacity iPhone 4 will be ready for launch within weeks.
When the iPhone 4 was officially launched by Apple, an 8GB 3GS model was released for a cheaper price. It seems logical for this to happen again after Apple's new iPhone is announced.
Also according to Reuters sources Apple is aiming at a September launch for the iPhone 5 (or 4S), which will supposedly have a bigger display, a revamped antenna design and a better 8MP camera. Apple is rumored to have assigned production of their next iPhone to two manufacturers - Pegatron and Hon Hai, and the total number of planned devices should be around 45 million.
There's not long left now until September 7th, which is the go-to rumor date for the big iPhone announcement by Apple. Fingers crossed!
