After having been halted by the iPhone 4S reality for some time, the rumor mills have back to the imaginary iPhone 5.  Many people believe Apple will launch iPhone 5 in 2012.

Though Apple hasn't given any hint about the possible features of the smartphone, yet many experts are predicting that LTE, or wireless broadband technology, may be added to iPhone 5.

They say Apple won't launch the iPhone 5 until the 4G LTE technology is available for compact smartphones. With the availability of LTE, upload and download speeds will be much faster compared to the existing 3G networks. As a result, the device may not be released until next year, they reason.

The lack of more compact LTE chips is to be blamed for Apple's release the iPhone 4S instead of the iPhone 5, according to analysts. It is reported that Qualcomm is working on a chip that will be ready by the second quarter of 2012 and could be used in Apple's next handset.

In the present situation, LTE chips will not fit into the casing of iPhone 4 after all other components are added. It has to be noted that iPhone 4 already uses a small printed circuit board that will leave little space for the LTE chip. iPhone 5 will not be able to fit an LTE chip without shrinking battery size, as of now. At the same time huge battery support will be required for the large number of applications.

Since iPhone 4S is out featuring a dual-core processor and an 8 megapixel camera, it can only be assumed that iPhone 5 will feature high end specs. A curved glass display and a slimmer body with an aluminum plate casing are also expected in iPhone 5.
