The legacy left behind by the genius, Steve jobs, is not limited to iPhone 4S. According to an analyst, the ultimate addition in Steve Jobs’ legacy will be the next iPhone, tentatively called iPhone 5.

The next-generation iPhone “was the last project that Steve Jobs was intimately involved with from concept to final design. For that reason…this product will establish the high water mark for iPhone volumes,” informed Ashok Kumar, an analyst at Rodman & Renshaw, in his recent weekly research note. He further predicts the iPhone 5 to be a “cult classic” because of Jobs’ involvement.

The research note also goes on to describe the features of the anticipated iPhone. Kumar believes that the new iPhone will have a slimmer profile and larger screen size but with the same dimensions as the iPhone 4S (like the relatively-small 3.5-inch screen is not one of the 4S’ best features). He also predicts that the iPhone will have LTE, or Long Term Evolution which is often referred to as 4G.

In fact the speculation is being believed to be true by many sources. Another source who claimed to have the knowledge about the redesign for iPhone 5 revealed that the iPhone 5 is a “complete redesign; this is a very large project that Steve dedicated all of his time to. He was not that involved in the 4S because his time was limited.”

The provisions for a complete redesign comes as good news to many, especially after iPhone 4S offered no considerable visual change. iPhone 4S, cosmetically is identical to the iPhone 4 and hence no big change there. And although iPhone 4S has been completely overhauled from the inside, but still carries the technology of iPad 2: the same dual-core processor, same memory capacity, same accelerometer, and same gyroscope, among other similarities. It looks like this will certainly be one of the best iPhone deals yet.

Thus probably it is much welcomed change if the rumors of a complete redesign are to be believed. Many sources claims the redesign will be both internally and externally, though less internally when compared to the physical changes like the display size. Perhaps the internal software will graduate to iOS 6 or Siri 2. Rumors galore but the only way to find out is with the launch of the new product. According to Kumar’s research note, the Apple iPhone 5 should debut around the time of Apple’s Developer’s Conference in the summer of 2012.
