Sprint has an upcoming $100 off deal coming up when you port your number and purchase an EVO 4G LTE or Epic Touch 4G. Normally that alone wouldn’t be that big but the ad for the promo outs an unannounced device. As you can see from the screenshot above, both devices are in white. Without saying much Sprint has just pretty much confirmed the existence of the white HTC EVO 4G LTE. We expect some sort of official announcement to be released soon.
