Dell through an FCC filing (PDF) has let slip that the new Mini 10 will soon get a version with WiMAX. The netbook should get Intel’s WiFi-Link 6250 and will incorporate both the 4G wireless as well as 802.11n Wi-Fi in a single chipset. No other obvious changes are present, though both are upgrades over the 3G and 802.11g of the current Mini 10.
The portable also doesn’t have a particular launch window, though the US-oriented CTIA show in late March is an early opportunity. It’s most likely the Mini 10 will be available in the US as an option for Clear or Sprint 4G customers, although it’s not certain that the PC would be available directly through the carriers instead of through Dell alone.
