After the 10.5.7 update I cannot connect my iPhone (3G with OS 3.0b5) with my MBP. It doesn't even charge. I tried the following: *iPod nano does sync/connect with this machine. *tried different cables/usb ports/used a USB hub. nothing. *resetted SMC/PRAM/NVRAM. didn't help. *reinstalled the latest iTunes 8.2b. nothing. *removed iTunes 8.2 and installed iTunes 8.1.1. same thing. *tried to connect to a different machine (mac mini with 10.5.6) and it worked. iPhone was charging and iTunes recognized it. My guess is either 10.5.7 or a problem with the drivers on this MBP. Any help is greatly appreciated! My hardware is a second generation MBP 2.16GHz. Update: I tried repairing permissions and reinstalling 10.5.7 as a combo update. Still nothing.
