At CES this year Samsung teased an Android 4G LTE phone with no-name that has 'gone under the radar' since then, but today it appeared in an FCC filing with the model number SCH-I510. A Verizon insider has indicated that this phone will be called the Samsung Stealth, which is rather appropriate. As you can see from the pic above it is a CDMA phone with LTE, which definitely lends credence to the Verizon tip. No other details are available for this 'phantom' phone yet, but we will keep you apprised as more info comes to light. Here's a video teaser below from CES.
