Yesterday we got a little hint from Verizon with a tweet saying the HTC Thunderbolt would be releasing soon. Today we wake up to find more confirmation that a release is imminent from next week's leaked Best Buy flyer. The advertisement introduces the 4G Thunderbolt by HTC and mentions that pre-orders will be available with a $50 deposit. A release date still hasn't been announced, but I have a feeling it's going to drop anytime. If you know something we don't be sure to let us know!
