Yeah… The latest Android 2.3.5 (GRJ90) Gingerbread is available on HTC HD2. What are Android 2.3.5 features? You tell me. Anyway, I am looking forward for Android 4.0 Ice Cream Sandwich (a combination of Gingerbread and Honeycomb) which should be available on Q4 2011. Here is the best Android 2.3.5 Gingerbread NAND Android ROM for HTC HD2. They are based on CyanogenMod 7, MIUI and AOSP stock Gingerbread for Nexus One.
