Hi there. My iPhone 4 has recently stopped tethering to my MBP through USB... Earlier in the week it was having issues tethering through Bluetooth (I would have to reset the Bluetooth on my MBP for it to connect) until it finally stopped connecting altogether. Tethering through wi-fi seems to be working fine, though. I did install a bluetooth program on my MBP (1Keyboard), but have since deleted it to see if it would fix the issue. Haven't made any major changes to my phone though. Has anyone had similar problems? I have held off from restoring the phone and resetting SMC or PRAM on the MBP in hopes of finding another solution. The iPhone is running version 4.3.3, Jailbroken. MBP is 15" early 2011, running 10.7.1 Any help would be appreciated.
