Almost everyday we come across some rumors about Apple’s new i-devices. However, on Monday a big bang came out. It said that Apple will surprisingly release two separate devices: one is the widely expected iPhone 5 and the other is an improved version of iPhone 4, called ‘iPhone 4-plus’.

According to a report by Fortune and CNN Money, Mark Moskowitz, a J.P. Morgan analyst, has done a report in which he described Apple’s possible launch plan.

Our research indicates that there will be an iPhone 5 based on a lighter, thinner form factor that is GSM + CDMA capable, i.e., a 'world-mode smartphone,' Moskowitz wrote. A second device (4-plus) based on the current iPhone 4 but with some minor improvements could target the midrange and focus on China. As for the current iPhone 4, we expect it to subsume 3GS as the lower-end offering.

This idea is not a groundless conjecture. Actually new photos of about a half assembled iPhone 4 plus have already been released on Chinese site Weibo. These photos show that the so-called iPhone 4-plus has an A5 processor and a 3.7 V battery which provides 1430 mAh of charge although its internals are almost identical to that of the current iPhone 4.

There is a mild increase compared to the current iPhone 4 whose maximum charge available is 1420 mAh.

Meanwhile, a rumor is spreading like wildfire that iPhone 5 will have an A5 processor and a bigger screen. If the rumor is true, it will be reasonable to believe that the battery will be relatively larger. With an A5 chip as an enhancement and a nearly same form factor as iPhone 4.

Apple is not in a rush to release new devices since its product is facing lackluster competition. Although the speculation has into run months regarding the launch announcement of its new iPhone, it seems that we still have to wait a bit longer.
