I recently did the 2.3.3 update on my HTC Inspire 4G and I can't get the free wifi hotspot anymore. Before I changed the APN setting to enable the WiFi hotspot without charges but now with the same settings it doesn't work. Also a lot of lag with the phone. Also when I press the Home, menu, Back, and Search Buttons they sometimes vibrate and sometimes they dont. Id like some help so any suggestions are welcome.
