With the release of the new iPad, 2012 version, Apple, Inc. has released an update to the iOS 5, the 5.1. The important thing is that it is compatible to every iOS device that could run iOS 4 or iOS 5. However, the new update has given iPhone 4S users a new problem to deal […]

Has the iPhone 4S really turned into a 4G device? – The real story unveiled – Part 2

In other words, the iPhone 4S offers a slight speed boost over the iPhone 4 and other 3G devices. But I wouldn’t say it’s significant enough to put it in the same class as devices operating on a 4G LTE network or even devices operating on the newest and fastest versions of HSPA+. But is […]

According to the ITU’s initial IMT-Advanced specification, for a technology to be considered “4G” it must deliver downlink speeds of 1Gbps when stationary and 100Mbps when mobile.

Nokia Lumia 900: Full Review (2012) – Part 2

Having said that, Lumia pack a punch in its unibody structure that deliberately comes in some flashy colours like Magenta, for example. Its lightly sculpted chassis and deliberate use of coloUr scream “lifestyle product.” Bold as an exclamation mark, the Lumia 900 has pure pop-art coursing through its electrical veins. The chassis has a perfectly […]

Nokia Lumia 900: Full Review (2012) – Part 3

In both brightness and richness, the Lumia 900 absolutely blows away the Focus S, which at the time I hailed as a beautiful Super AMOLED Plus screen in its own right. At the same levels of full and automatic brightness, the Lumia 900 shone about a full level brighter than the Focus S. Beyond the […]

Nokia Lumia 900: Full Review (2012) – Part 4

Wi-Fi, GPS, and Bluetooth are standards, though sadly, the Lumia 900 ships with Bluetooth 2.1, practically antique compared with the new Bluetooth 4.0 standard we’re starting to see in mobile devices. Nokia boasts that its 8-megapixel camera on the Lumia 900 has Carl Zeiss optics, which, along with its dual-LED flash and autofocus, are meant […]

Nokia Lumia 900: Full Review (2012) – Part 5
