We don't know whether Nokia is disturbed with the news of iPhone 5 release or with Samsung's launch of Galaxy S3. But all we know is that with Lumia 900, Nokia is planning something big this time.

Nokia's flagship Lumia handset, the Lumia 900, which was unveiled at the CES earlier this year, was described by Chris Weber, President of Nokia in North America, as iconic, beautiful and fast. It is the company's first 4G Long Term Evolution (LTE) phone.

This special Lumia phone will enjoy a special launch on April 8, reveals AT&T device head Jeff Bradley.

At all levels, this is a notch above anything we've ever done, AT&T Bradley said in an interview with CNET, and that includes the launch of the iPhone.

While the Nokia phone is enjoying the limelight, Samsung is also gearing up to launch its best weapon, the S3. But before phasing out the S2, the Korean electronics giant has provided the 'killing' upgrade to the phone, Ice Cream Sandwich.

The cool Ice Cream Sandwich has surely increased the hotness quotient of S2, which is already known as the 'best Android phone'. 

How effective is the last moment ICS upgrade for Galaxy S2? Can it beat the windows phone Lumia 900?
