I was talking to AT&T yesterday and wanted to upgrade to a tethering plan on my iPhone but they said I would lose my Unlimited Data Plan. The other option was to Jailbreak which I am not full comfortable with. The third option is to get a Dev account and upload the source code from iProxy that can be found on the internet onto my iPhone. Do you think this will work? What level of difficulty would you rank this at. I am somewhat computer knowledgeable but definitely not a golden boy. I was obviously going to do this to my "Daily Driver" iPhone and only use it on Limited use. Not stream netflix all day and burn through data and make it obvious to be caught by AT&T. Do you think it would be stable enough to run. I would be completely fine with running iOS4 instead of the rumored shaky iOS5.
