The Mesmerize is the US Cellular version of Samsung's popular Galaxy S lineup. It's a CDMA Galaxy S that resembles the Fascinate on Verizon. The difference between the two is that the Fascinate comes with Bing and this does not. 

Here are the specs:

• 1GHz Hummingbird processor
• 4-inch Super-AMOLED screen
• 5MP camera
• Android 2.1 (Eclair)

It's a solid Android phone for US Cellular customers.
