An FCC filing from Dell leaked some new information about the new Mini 10 that is expected to be released later this year. The upgraded netbook will feature Intel’s latest WiFi-Link 6250, which incorporates 4G WiMax and 802.11n wireless support onto a single chip.

There are still some details missing such as an expected launch date and what, if any, other upgrades can be expected to the existing hardware. It can be expected that Dell will launch the WiMax models with compatibility with Clear and Sprint, as they are currently the only widely available 4G network providers.
