HTC's 7-inch Flyer tablet is the latest device to find itself with an unlockable bootloader, courtesy of the official HTC development website. Added to the bottom of the list of unlockable devices over on HTCDev.com are various flavors of Flyer, including the international Wifi-only and 3G versions. Before you start, you'll want to double-check which Flyer model you have, and also ensure you're on the correct firmware version, as you'll need to be fully up-to-date in order for the web tool to work its magic.
Conspicuous in its absence is the EVO View 4G, the Wimax version of the tablet that launched on Sprint around the same time as the Flyer released globally. Given that the Sprint EVO 3D is already unlockable through HTCDev.com, though, we'd expect to see it on there sooner rather than later.
Unlocking your device's bootloader will allow you to install custom firmware that hasn't been approved by HTC like the official software. As ever, unlocking should only be attempted if you're comfortable with monkeying around with the software internals of your device, and you'll void your warranty, even if you use the official HTC tools.
