I searched and haven't seen this problem posted anywhere so here goes. I'm on a iPhone 4 5.0.1 jailbroken and MyWi works, in that it lets me tether to my laptop, but it does not let me use the 3G functions on the phone itself. Also, when I turn MyWi off, the phone's 3G functions don't work at all without a restart. It will show 5 bars 3G reception but no internet connection will be made. Thoughts?
