It's been a while since we've gotten a tip about the HTC Thunderbolt, but it looks like we have something new to show you. Thanks to one of our loyal tipsters we now have a pic of what the HTC Thunderbolt might cost you if you don't have an upgrade. According to the picture we were sent the TBolt is going to set you back a good $749! Usually a smartphone outright is $599, but if this picture holds true you are going to be forking out more then that if you get it from Best Buy. Now this price is just if you don't have an upgrade, or signing up for a NEW 2-year agreement. Look at it like this, if you get Best Buy's free buy back on it right now that could be some serious money back when it comes time for a new phone. Thoughts or concerns?
