Apart from Apple Inc.'s iPhone 5, the most awaited Android smartphones are Samsung Galaxy S2 and Motorola Droid Bionic.

The much-awaited Samsung Galaxy S2, which sold about 3 million units worldwide, may hit the U.S. smartphone market on July 21. According to a listing that appeared briefly on Best Buy Canada, Canadian mobile provider Bell is set to launch the anticipated Samsung smartphone on July 21, Endgadget reported.

The page has since been pulled off, but when it was live, it showed that the Samsung Galaxy S2 had been priced at $150 with a three-year commitment, which later increased to $170. If this is true, then Bell will be the first North American carrier to sell one of the most coveted Android smartphones on the planet.

Recently, Motorola Droid Bionic was spotted with a Best Buy Mobile promotional shot that is traversing the Web. The leaked promo described Droid Bionic to be a ferocious force and an unstoppable powerful device. But, the biggest question remains whether the smartphone will last even if it makes a splash in the beginning. If we consider HTC Thunderbolt 4G LTE smartphone, it was in fact outselling even Apple iPhone 4 for a while at Verizon.

Motorola confirmed via Twitter that its much anticipated Verizon LTE phone will arrive this summer.

Galaxy S2 will be coming in four versions in the U.S. -- Function at Verizon, Attain for AT&T, and Within for Sprint Nextel, and a T-Mobile version. Motorola Droid Bionic will only be featured in Verizon.

Motorola Droid Bionic is a candy bar-style smartphone with support of modern 4G technology from Verizon LTE network. The phone seems to be strong and portable with Android 2.2 Froyo installed in it. It can be easily upgraded to 2.3 Gingerbread anytime. If the battery life clicks for Motorola Droid Bionic, then most probably Samsung Galaxy S2 will have very stiff competition from it.
