I'm sorry to bother you guys but whatever I try in regards to getting tethering to work it just simply won't work. I did the install MyWi and then delete bit and that worked great but a couple weeks later, I tried tethering and when I enabled it the option just disappeared from network settings. I tried reinstalling MyWi but my trial is up. I tried the Benm way and the tethering option reappeared but when I hooked it up to my computer and hit enable, the option disappeared again. I even went as low as getting the cracked version of MyWi off Cydia and STILL the option would appear and when enabled...would disappear. Does anyone have a solution to my problem? Thanks again in advance for the response. I have an iPhone 3G running 3.1.2. Also, I have gotten my iPhone to tether via bluetooth just not USB. I have a Mac running Snow Leopard anyone have any ideas on fixing that issue?
