A short while ago, the Best Buy Grand Rapids Facebook page prematurely posted a status update indicating the release dates of the Motorola XOOM tablet and the HTC Thunderbolt.
The status update suggests that the Motorola XOOM will be available for sale at Best Buy from February 24, while the HTC Thunderbolt will be available starting February 14 (the day after Mobile World Congress 2011 officially kicks off). Additionally, the Verizon iPhone 4 will be coming to Best Buy on February 10, and the Samsung Presto 4G LTE Mobile Hotspot will be available from February 17.
A Facebook page of a Best Buy outlet does not seem like the most appropriate place to disseminate information on release dates; however, we have also received independent confirmation from a reliable source indicating that the HTC Thunderbolt will go on sale online on or around the date mentioned in the Facebook message.
A recently leaked advertisement on Android Central also informs us that the HTC Thunderbolt will be available for pre-orders with a $50 deposit.
It's important to keep in mind that since the release dates indicated on the Facebook status update are quite near, they may be actually be the dates from which the devices can be pre-ordered rather than the actual date of release.
