Good and bad news for U.S. Cellular customers: the carrier will be getting a Windows Phone device, by HTC, but unfortunately you may have a few more months to wait as they are being hush-hush on the matter.

According to a press release, U.S. Cellular is finally looking to bring over the nearly 1-year old OS:

CHICAGO (June 09, 2011) – Between now and the end of the year, U.S. Cellular (NYSE: USM) is expanding its portfolio of cutting-edge devices with more features, handset styles and pricing options to help its customers select the one that meets their needs and helps them stay connected.

U.S. Cellular plans to launch seven smartphones that run on the Android™ operating system, including its first 4G-enabled smartphone. Two mobile tablets are planned along with the carrier's first Windows® Phone 7 device. U.S. Cellular will also roll out its first wave of 4G LTE devices in November.

...U.S. Cellular plans to launch four devices from HTC Corp. beginning this summer, including the carrier's first Windows Phone device that runs the Windows 7™ operating system. The Live Tiles on the Windows 7 homescreen show all of the messages, voicemails, e-mails and social network status updates in a single glance.

No word on which device exactly they are getting: Trophy, Arrive/7 Pro or HD7, but hey, at least there's light at the end of the tunnel for those folks still on contract on the carrier.
