Hey I got a solution to the Local only HTC Touch Vouge from Sprint(not to be confused with the Verizon phone of same name different model) issue. You have to manually put the proxy settings on your browser as the phone is obviously not handling the settings for this properly. If somebody has a patch for this please post it but otherwise my tethering works. In IE just go to your internet options> connections tab> Lan Settings button > cehck the use proxy and enter wap.metropcs.net and 3128 for the port and BAM internet. Similar works for Mozilla as well. I felt stupid too.
