My home broadband connection is down. Luckily, I have HTC HD2 with me. I can do Wi-Fi and USB tethering in Windows Mobile. But some of the Android ROMs cannot do both. So here is an Android application that can help those who like me ~ Wireless Tether for Root Users. It enables tethering via Wi-Fi or Bluetooth. I did not try on Bluetooth mode but I am a happy user with Internet connection through Wi-Fi.
