Here's my situation. My gf has an WIFI IPad 2 and a 3G iPhone with no data plan. So i wanted a way permanently turn on my personal hotspot (on an iPhone 4)so that she could use my 3g connection whenever she wants when we're spending time together without me having to turn it on and off. Yes, i could just leave it on the whole time. But then whenever I plug my iPhone in to my MBP for iTunes sync/charging purposes, the personal hotspot triggers and start sharing my 3G data to my laptop through USB. Now I have to turn it off. And next time when my gf wants to use my data, I have to turn it on again. Is there a legit/apple way to set the personal hotspot permanently on AND USB tethering permanently off at the same time? I mean, in the rare case where I need to tether my MBP, i could still join my personal hotspot with WIFI(not through the wire) right? If not, is there a cydia tweak to do that? I tried both SBSettings tethering toggle and the personal hotspot toggle. They don't really work the way I wanted it to. Suggestions?
