I tether my iPad to my iPhone5 for use during the day and around town. Prior to the iPhone 5 I was tethering to my 4 via a jailbroken tether app. Now that I have the mobile share plan, I have gone legit and am using the built in tether capabilities. When I tether over wifi, I have no problems, but when I tether over bluetooth, my iMessage can't send or receive messages. I also think there may be an issue receiving notifications while tethered over bluetooth. Everything else works fine, safari, facebook, etc. Any help/suggestions?
