The launch of the next generation iPhone, dubbed iPhone 5, is being highly awaited and with so many high-end Android smartphones (aka superphones) out (and ready to be out) in the market, smartphone users are spoiled for choices.

According to the latest market research data, Android smartphones have grown to become more popular than the iPhone and, according to Google, over 500,000 Android devices are being activated everyday.

However, iPhone continues to be the gold standard for the smartphone industry and according to market rumors, iPhone 5 will boast of radical new design that will incorporate Aluminum metal backing of the original iPhone instead of the current glass surface back piece. The new iPhone is also expected to come in a SIM-less design (to give it world phone capability) and sport a teardrop design, like the new iPod Touch, with the top being thick and then tapering to a skinnier bottom.

Other expected iPhone 5 features are:

> A5 processor in the range of 1.2-1.5 GHz
> An improved antenna (iPhone 4 users no more Antennagate, yay!)
> More RAM, possibly 1GB
> Bigger-edge-to-edge 3.7- to 4-inch curved glass screen (iPhone 4 has 3.5-inch screen)
> 3-4 internal antennas for both GSM and CDMA networks
> 4G connectivity
> iOS 5, which will be true multitask capable and come with loads of new features such as News Stand, Reminders, Delta Updates and iMessage
> Improved speech recognition features, and
> Wireless charging capability
> Better talktime and standy time
> Near Field Communication (NFC) technology
> Panoramic photo capabilities and 1080p Full HD videos
> More powerful gaming capabilities supported by multi-core A5 processor and Imagination Technologies' PowerVR Series6 mobile graphics processing architecture

Impressive specs but iPhone 5 will face a tough challenge from a string of Android superphones, which have already hit (or are set to hit) the US market.
