I did, I got this phone and turned in my Incredible. I live in Brooklyn, NY, so I have steady 4G coverage. I actually thought the Incredible had worse battery life then this Thunderbolt. I got the extended 2750 battery for the Incredible and so I got it for the Thunderbolt too. It actually makes less of difference on the Thunderbolt then the Incredible. Because the Incredible felt like a think light phone and the extended battery turned into a thick heavy phone. On the other hand the Thunderbolt is already a large heavy feeling phone, so the extra girth and weight doesn't seem like a big deal, making a heavy phone a bit heavier.
