T-Mobile: HTC Amaze and Samsung Galaxy S II go on sale Oct. 12

T-Mobile USA on Monday unveiled its two fastest 4G smartphones, both of which have dual-core 1.5GHz processors and go on sale Oct. 12.

The two new devices are the HTC Amaze 4G and the Samsung Galaxy S II. T-Mobile will sell the Amaze for $259.99 and the Galaxy S II for $229.99. Both prices reflect a $50 rebate and are only available to customers who sign up for two-year service contracts.

They will be the first T-Mobile smartphones to run on the carrier's latest 4G network, HSPA+42, which has a theoretical top download speed of 42Mbps. T-Mobile said average downloads on the network approach 8Mbps.

What most distinguishes the devices, however, is the Qualcomm Snapdragon S3 chip, a 1.5GHz dual-core processor. The Amaze runs Android 2.3.4, also known as Gingerbread, while the Galaxy S II runs Android Version 2.3.5.

Both phones support near field communications technology, which is being used in some emerging "mobile wallet" systems in which smartphones are used to pay for purchases in retail stores.

Pre-sale online orders will begin Oct. 10. The devices are expected to be in T-Mobile stores and on other retailers' shelves on Oct. 12.

The Amaze will be a T-Mobile exclusive. It features an 8-megapixel camera and a full HD 1080p camcorder, with an embedded video editor. It comes with a 4.3-in. touchscreen.

Samsung Galaxy S II

Samsung said the T-Mobile version of the Galaxy S II has a 4.52-in. touchscreen, the largest of any smartphone sold by T-Mobile. Samsung said it has sold 10 million Galaxy S II smartphones worldwide, although the devices vary somewhat from carrier to carrier and from country to country.

This Galaxy S II from T-Mobile offers a faster processing speed than the Galaxy S II Epic 4G Touch from Sprint, which has a 1.2GHz dual-core chip.
