AT&T is taking pre-orders for the Samsung Galaxy S4, $639 upfront or $199.99 on a two-year contract ...

The 16GB version of the Samsung Galaxy S4 is now available to pre-order on the AT&T website, both in the White Frost and Black Mist color schemes for $199.99 on a two-year contract. A SIM-free version will set consumers back a hefty $639, however.

AT&T has yet to make an official announcment; perhaps to avoid an overload of pre-orders, given that we’ve already experienced some problems trying to access the webpage and complete an order. The 32GB version is also unavailable at this point.

The US carrier will be shipping all Galaxy S4 pre-orders by April 30, arriving on consumer doorsteps shortly afterwards. It’s a short gap between the launch of the HTC One, which is launching on April 19 for $199.99 as the standard 32GB model and $299.99 for the 64GB variant.

AT&T is already taking pre-orders for HTC’s flagship device, although there’s no way of knowing how much of an impact its head-start will have on sales figures.

The Samsung Galaxy S4, unveiled in March, will go head-to-head with the HTC One, as well as the next iPhone and Nexus smartphones that will inevitably be released later this year.

The device has a premium 5-inch 1080p display, set at an impressive 441 ppi. Under the hood is a quad-core 1.6 GHz Cortex-A15 processor, bumped up by an additional quad-core 1.2 GHz Cortex-A7 chipset. That’s a whole lot of processing power.

The Galaxy S4 comes stocked with 16GB of internal storage, although that’s expandable via a microSD card, and runs on the latest version of Android (version 4.2.2) with Samsung’s TouchWiz skin slapped on top.

The device also has a mighty Li-Ion 2600 mAh battery, which should do a pretty decent job of counterbalancing the smartphone’s power-hungry processors, and 2GB of RAM handling multiple apps and tasks.

Pre-orders for the device opened in the United Kingdom late last month, ahead of a public release on April 26. TELUS, Virgin Mobile and Bell opened pre-orders in Canada yesterday, ahead of a full retail launch on May 3.
