Boost Mobile fans received very good news on Wednesday, Aug. 22, when the carrier announced a slew of Samsung devices coming this fall. The biggest of the three handsets the carrier unveiled at its media event in New York is the Samsung Galaxy S2 4G, which will retail for $369.99 without a contract when it is released on Sept. 6.

The handset is a 4G variant of last year's most impressive Android smartphone. Prepaid carriers used to get only handsets that postpaid carriers did not want, leading to an "okay" selection, but nothing impressive. Users who wanted a phone without committing to a contract had to settle for what carriers had to offer, and the prepaid selection bore no comparison to the handsets available on postpaid operators.

With Boost's new lineup, however, that may be about to change. The Samsung Galaxy S2 4G is still a very impressive smartphone, even if it is last year's iteration. It sports a 4.5-inch Super AMOLED Plus display, 1.2GHz dual-core Exynos processor, 16GB of storage, 1080p movie mode, an 8-megapixel rear camera, 2-megapixel front camera, WiMAX/EVDO-Rev A. radios, and a 1800mAh battery. Boost is the first no-contract carrier in the U.S. to offer the Galaxy S2 4G.

"Together with Samsung we continue to launch compelling device options from entry-level to 4G-enabled smartphone to meet the evolving needs of our customers," said Boost Mobile's vice president Andre Smith. "Launching the award-winning Samsung Galaxy S II 4G marks a defining moment for Boost's customers craving a portable entertainment powerhouse and a no-contract unlimited plan that shrinks to as low as $40 a month."

In addition to the Galaxy S2, Boost Mobile is also offering the Samsung Galaxy Rush and Samsung Array, two affordable, low-end Android handsets. The Samsung Galaxy Rush comes with Android 4.0 Ice Cream Sandwich and will sell for $149.99 in late September. It packs a 3.5-inch display, a 3-megapixel rear-facing camera, and a 1.3-megapixel front-facing camera. Meanwhile, the Array will come on Sept. 4 at the lower end of the line, with a $59.99 price tag, and will feature a full slide-out QWERTY keyboard, a 2-megapixel rear camera and a 2.4-inch LCD screen.

All three handsets can be purchased and used with Boost Mobile's Shrinking Payments option. "For every six on-time payments, the cost of Boost Mobile's Monthly Unlimited plan shrinks by $5, eventually getting down to as low as $40 a month for unlimited talk, text and data," touted the carrier.
