This thread is for Mac OS X Leopard users and iPhone owners. Since you upgraded to 10.5.6, have you been able to put your iPhone into DFU mode and still have iTunes recognize it? I heard on TUAW today that DFU mode no longer works with 10.5.6, but since I've upgraded to 10.5.6, I've QuickPwned a first gen iPhone with DFU mode and an iPod touch in DFU mode. So my answer is: Yes, DFU mode still works for me in 10.5.6. I have not tried the iPhone 3G yet. I'd like to get the communities findings on this one because I'm curious as to why DFU mode still works for me when TUAW says it won't. Here's the article. Thank you.
