Did you know that the HTC HD2 ships with a WiFi 802.11n adapter? The capability of this adapter is restricted to 802.11g to save battery life. But for those of you who want blazing fast wireless transfer speeds on your HTC HD2, here’s a simple hack discovered by XDA developers which enables WiFi 11n.
To enable 802.11n, use a registry editor and go to hklm/comm/bcmsddhcd1/parms and set 11nModeDisable=0
[This tweak requires registry modification, if you brick your phone, I or this blog will not be responsible]
Note that the battery life might take a hit by enabling WiFi 11n, but then anything goes for bragging rights in front of your iPhone 3G S using friends who are stuck with 802.11g.[via HTCPEDIA]
