Sprint 3G /4G USB Modem U301
A new hybrid 3G / 4G modem is coming from Sprint soon. This device will replace the U300 that is currently shipping now. We expect this device to offer full Mac Support along with hybrid 3G/4G support. When you are in a 4G native area, you will get 4G speeds, when you are not, the modem will drop down to 3G.
