T-Mobile will launch online sales of the Samsung Galaxy S2 and HTC Amaze on Oct. 10 with the in-store sales beginning Oct. 12, T-Mobile USA Chief Marketing Officer Cole Brodman said in a statement.

From the GigaOm Mobilize 2011 conference in San Francisco, Calif. Monday, Brodman announced both handsets are intended to take advantage of T-Mobile's upgraded network and they both offer 8-megapixel cameras on the back, a move intended to bring new smartphone users to the company. Anyone who signs a new two-year contract can get a $50 rebate on either phone, bringing the Samsung Galaxy S2 price to $229.99 and the HTC Amaze to $259.99.

The release date could come only days after Apple unveils its widely anticipated iPhone 5, so T-Mobile could be betting on huge consumer interest to give them a bump in sales. Additionally, worldwide sales of the Galaxy S2 have already hit 10 million units, so the U.S. release would give T-Mobile another bump in the ever escalating smartphone shootout.

Both the Galaxy S2 and HTC Amaze boast dual core processors that come close to rivaling desktop processor speeds.

These new products unlock the full potential of our faster 4G network and deliver the best experience yet for watching video, surfing the Web, and creating and sharing content on the go, said Brodman,

While the HTC Amaze will be exclusively offered by T-Mobile, the Galaxy S2 has already been released on the Spring network, albeit with a slightly slower processor speed. Another bonus for T-Mobile buyers here is that the Amaze includes a Near Field Communication (NFC) chip for future mobile payments (think Google Wallet).

Whether or not the AT&T/T-Mobile merger goes through, this release should carry T-Mobile through the rest of the year or until the next round of smartphone shootout goes live.

We're offering what we believe is the best 4G product portfolio in the industry, Brodman said.
