It's been seen on Alltel, Bluegrass Cellular and deep inside Verizon stores, and now US Cellular has the Samsung Gem. As you'll recall, it's a mid-range 3.2-inch (WQVGA display) Android 2.2 device with a 3.2MP camera and 800MHz processor.
The Gem will be available on April 1 for a mere $29.99 after $80 mail-in rebate.
