Here’s some speculative information on a handset we’ve been calling, up to this point, the HTC Incredible HD. The HD has not had the stealthiest pre-release life. You may remember that we first spotted the device way back in August and pegged it for release on U.S. carrier Verizon Wireless. Just last week, the device made a handful of cameos on various technology sites thanks to, what appeared to be, a controlled leak. Fast forward to today, and an ad campaign being run on blog Android Central may have revealed the handset name that HTC plans to go to market with. That name is… Thunderbolt 4G. An advert displayed on the site that mirrors the one pictured above directs users to a non-working website with the URL http://www.htc.com/4G?extcid=Thunderbolt-4G-Disp. Now, we’re obviously making some assumptions based on the URL string, but it doesn’t seem to be too out of whack with HTC’s naming conventions. What do you think of the name Thunderbolt 4G?
