Well, right after they confirmed that it was coming this month then releasing the changelog, HTC and Verizon have just rolled out the Gingerbread update for the HTC Thunderbolt, finally! This much needed software bump will bring many enhancements and bugs fixes to Verizon’s first ever 4G LTE-capable phone. If you haven’t gotten the prompt yet, we suggest that you manually look for it by going to Settings > Software Update > Check New. Your Thunderbolt Android OS version will change to Android 2.3.4.
