Samsung Jasper is a mid range 4G smart phone for Verizon that is being rumored from quite sometime. The specs of Jasper include Qualcomm Snapdragon S4 processor, which is being used in US version of Galaxy S3 and HTC Droid Incredible 4G LTE as well. However, unlock aforementioned phones, its CPU will run at 1.2GHz perhaps to prolong battery runtimes.
The original clock speed of the CPU is 1.5GHz. The screen size is unknown (looks like 4 inches from its picture) but we do know it packs 800 x 480 pixels resolution, which is normal for a mid range phone like this. As expected, the Samsung Jasper will run Android 4.0 ICS. It will also have a dedicated key for doing multitasking.
