Ah yes, the HTC ThunderBolt. This beast of a device was merely a single core blazing fast phone which was sought after for months. I personally love mine. Haven't rooted it yet, but now I might have a good reason to do so.
Recently we have covered a story on the ThunderBolt being overclocked to 1.8 GHz. Now it blows past that at a speed of 2.016 GHz. Keep in mind, the phone can't run stable at these speeds. That's probably obviously why it wasn't launched running that fast, although, according to Derek Rodriguez (@drod2169 on twitter), his ThunderBolt has run at a stable speed of 1.996 GHz.
I would highly, highly not recommend you overclock your phone at these speeds, unless if you lost power or gas in your house and need something to boil a pot of water on. Will you be brave enough to try it out? Let us know. Here's one of his tweets below.
