Samsung's new flagship phone, the Galaxy S4, will make its debut in the US next week.

Pricing and availability vary a bit carrier to carrier, but here's what we know so far:

• T-mobile will begin selling the Galaxy S4 on April 24. It'll cost $149.99 up front, plus $20 per month for 24 months.
• AT&T is now accepting pre-orders for the Galaxy S4, starting at $199.99 with a two-year contract. We're still waiting for a launch date.
• Sprint will sell the Galaxy S4 on April 27 for $249.99 with a two-year contract. New customers switching from another carrier can get the phone for $149.99.
• Verison has not announced pricing or availability for the Galaxy S4, but has confirmed it will sell the device.
• U.S. Cellular has not announced pricing or availability for the Galaxy S4, but has confirmed it will sell the device.

32GB HTC One Coming to AT&T and Sprint on April 19

AT&T and Sprint recently announced, albeit separately, plans to begin selling 32GB HTC One smartphones starting April 19 for $199.99 with a new two-year contract. In addition to that, AT&T said that it will be the only carrier in the United States to launch a 64GB version of the HTC One. That version of the smartphone will sell for $299.99 with a new two-year contract.

T-Mobile also announced that it will begin selling the HTC One "sometime in the spring", and said that it will charge $99 down with 24 equal payments of $20 in a low-subsidy, no contract plan. Online reservations for AT&T's HTC One began Thursday, April 4. Sprint began reservations on Friday, April 5.

AT&T will also be offering a free HTC Media Link HD wireless HDMI adapter with the device for a limited time. The device will allow you to connect your HTC One to an HDTV. However, you will also have to sign a separate two-year agreement for the adapter as well. AT&T and Sprint also confirmed that the HTC One will be available in both black and silver.

The HTC One comes with a 1.7 GHz quad-core processor, an aluminum case and has a 4.7" full HD screen. It comes equipped with Android 4.1 for its operating system as well as a new HTC Sense interface that is comparable to the tiles used in the Windows Phone 8. The device will also run on AT&T and Sprint's LTE wireless networks and comes with a 2300 mAh battery.

The only carrier to not announce availability for the HTC One was Verizon, who declined to comment on plans for the smartphone. It seems unlikely that the carrier will have the device, especially considering the fact that HTC doesn't list Verizon as a carrier on its website.

When the device was announced back in February, one of the biggest innovations that HTC was highlighting was the Ultrapixel camera. This camera has been designed to take better photos in low light than traditional cameras and is rated at 4 megapixels. However, HTC argues that it is capable of capturing more light and uses fewer, though larger, pixels for better pictures.

Like I said earlier, reservations for the HTC One are available on AT&T and Sprint, so if you've been waiting for the opportunity to get yours, then don't wait any longer! Head on over to AT&T or Sprint's website and reserve yours before they all run out!
