The Acer Iconia Tab A501 4G version was just announced to launch for AT&T. The 16GB version of the new tab will arrive on September 18th for $330 bucks on-contract, or $480 with no contract. To be clear, this version does not come with an LTE radio, but will instead use AT&T's older and slower HSPA+ network. According to the Engadget article, this press release below isn't 100% accurate. Supposedly, AT&T will only be selling the 16GB version at first, and it will be $480, not $499, without a contract. Here's the full press release:
MAXIMIZE ENTERTAINMENT ON THE GO WITH THE
NEW ACER ICONIA TAB A501

Acer's Popular 10.1-inch 4G Tablet with Android 3.0 OS Coming Soon to AT&T Retail Stores Nationwide and AT&T | Cell Phones, U-verse, Digital TV, DSL Internet, and Phone Service

DALLAS, Sept. 12, 2011 - AT&T* today announced it will begin selling the Acer Iconia Tab A501, a 10.1 inch, AT&T 4G** mobile broadband capable tablet featuring Android™ Honeycomb, online at AT&T | Cell Phones, U-verse, Digital TV, DSL Internet, and Phone Service and in AT&T company-owned retail stores nationwide beginning Sunday, Sept. 18.
Designed for both consumers and small businesses, the newest wirelessly enabled member of the Acer Iconia family of tablets gives customers the freedom to enjoy technology around the clock on the AT&T mobile broadband network. AT&T's HSPA+ technology with enhanced backhaul provides up to 4 times faster data transmission than AT&T's already fast mobile broadband network.

The tablet's 10.1-inch multi-touch screen provides precise finger-tip control for leveraging social media, email, productivity applications as well as games and entertainment. Powered by a NVIDIA® Tegra™ 2 mobile 1GHz dual-core processor and integrated GeForce™ GPU, customers can enjoy high-definition video, speedy browsing, multi-tasking, digital media playback and flash-based sites, games and applications.

"For tablet users it needs to be always on, connected, and readily available to access the content they want, including entertainment, social networking, email and Internet browsing," said Glenn Lurie, president, emerging devices, AT&T. "We're connecting the Acer Iconia to the AT&T 4G network and we're offering several data options, both prepaid and postpaid plans, to ensure the best experience, the best value and the greatest flexibility for our consumer and small business customers. We also plan to prominently feature the Acer Iconia in our AT&T stores across the country."

"Fast and fluid, the Acer Iconia Tab A501 is one of simplest ways to stay informed and entertained whether it's playing games or viewing a video on its high resolution capacitive touchscreen," said Sumit Agnihotry, vice president of product marketing, Acer America. "This tablet is not only intuitive, but it's svelte, stylish and comfortable to hold and carry, which appeals to consumers on the go."

The Acer Iconia Tab A501 will be available at AT&T company-owned retail stores nationwide and online beginning September 18 for $479.99. AT&T customers may also choose to purchase the Acer Iconia at a discounted price of $329.99 after committing to a two-year agreement for a new $35, 3GB monthly data plan.

Customers who do not choose a long-term commitment may still select one of two existing monthly billing options:
- Postpaid: $14.99 for 250 MB or $25 for 2 GB. Customers on the 2 GB plan who exceed their monthly data allotment will be charged $10 per 1 GB of overage. Customers on the 250 MB plan who exceed their monthly data allotment will be charged $14.99 per 250 MB of overage. Charges will appear on customers' monthly wireless statements.
- Prepaid: $14.99 for 250 MB or $25 for 2 GB. Customers on the 2 GB plan who exceed their monthly data allotment may choose to purchase an additional 2 GB for $25. Charges will appear on customers' credit card statements.
Offering the simplicity of a single bill, the postpaid option will show up on customers' monthly wireless bill after the data is used. The new postpaid billing option will be available online at AT&T | Cell Phones, U-verse, Digital TV, DSL Internet, and Phone Service and across AT&T retail locations.
