No Turn-By-Turn Navigation Feature For Apple IPhone 4

Apple at last took an audacious step at WWDC earlier this week by ditching Google Maps as the default mapping provider on iOS. Because of this change, iOS 6 will finally incorporate turn-by-turn navigation feature. iPhone users were in demand for this application for years and when it is going to be added, it seems that not all the users will get the chance to enjoy this turn-by-turn comfort. It is also stated that iPhone 4 and earlier device from the company won’t receive this feature.

On its official website, Apple has confirmed that the devices operating on the A5 or A5x ARM processors would be restricted to some of the mapping features. Apple iPhone 4 functions on the A4 chip that is a single-core 1GHz processor along with a 45nm manufacturing process. The original iPad is also powered with this A4 chip. The A5 chip of Apple that is integrated in to the devices like iPhone4S and iPad 2 is a dual-core processor clocked to 1GHz per-core on either 45 or 32nm; however, this depend on the manufacturing date. The A5x is a 32nm ARM chip that is similar to the A5 but it comes with a much better GPU.

The latest silicon from Apple is certainly faster then the old ones, but here the question arises whether the difference relevant to the features being pulled. Apart from the turn-by-turn navigation, the flyover photographic map view is also restricted to the A5 and higher devices. Devices with Android operating system have been embedded with good turn-by-turn navigation ever since the Motorola Droid in late 2009. However, this Motorola phone only had a 550Mhz single-core processor.

It is just not acceptable that Apple can’t make navigation work on a device powered by a 1GHz single-core ARM chip. In the current mobile market even the low-end Android devices are imbibed with both turn-by-turn directions and Google’s 3D map view. It seems as if Apple notably curbed features back from the previous devices in order to drive adoption of the new. For instance Siri was set aside for the iPhone 4S despite it was extensively believed that the iPhone 4 was capable.
