A new handset built by Sharp has shown up for testing on the FCC website and is expected to be the previously leaked 2009 Sidekick LX. Other hints that point to this include the Danger logo being present on the FCC label, and the device's support of the 1,700MHz AWS spectrum, or the same band T-Mobile uses for its 3G network. T-Mobile is the carrier of previous Sidekick models.

Otherwise, the FCC report reveals the device, model number PV300, has GSM support and a Bluetooth compatibility. When the device will launch of what it will cost is not yet known, as neither Sharp nor T-Mobile have made any official announcement related to the handset. [via PhoneScoop]
