A latest rumor about the iPhone 5 says that iPhone 5 will be launched on all four major carriers including Sprint and T-Mobile to the mix. But the rumor is actually about the next iPhone. So will it be the iPhone 5 or iPhone 4S, it is still unclear.

According to CNET, the iPhone 5 will be available on many more networks. Specially on Sprint and T-Mobile in U.S. The main reason behind this step of Apple is being said that this would increase Apple’s market by 30-percent. Apple is trying to easily increase its user base by expanding to all four major U.S. carriers.

Recently it was also being said that Apple has placed quite aggressive hardware orders for the handset, requesting 25 million units be built in 2011. But were these orders for iPhone 5 or for iPhone 4S, it still remained unclear.

I also listened last month that Sprint’s research and development team was internally testing an iPhone. But at that time also it remained unclear that was it iPhone 4 or iPhone 5? It may also be possible that Sprint introduce the iPhone 4 around the same time as the iPhone 5 comes in Lime Light. But I am feeling like the next generation iPhone; iPhone 5 will be the first iPhone by Sprint.

So at the basis of all these rumors, one thing we can say very surely that at least one iPhone may come out in September. It may be iPhone 4S or may also be the iPhone 5. Rest is Apple’s wish. Lets see what comes out!
