So when did you do the BenM tethering hack? Did you do the MMS update last night and then did the BenM tethering hack today and you now have both MMS and tethering?See, I only just tried tethering after getting MMS for the first time last night. I seem to have lost USB tethering but BlueTooth tethering is working fine. I updated the carrier to 5.0 a couple weeks ago and restarted the phone and MMS worked instantly. I didn't have to do anything different to get tethering to work last night.
Have you tried BT tethering?
I don't have the toggle to turn it on anymore (so I can't do BT or USB), so I'll have to do the tethering hack again, but I'm wondering if that will disable MMS.
