Hi, I recently upgraded to Snow Leopard 10.6.8, and I did all the updates that were indicated. It now shows no updates available. ITunes is also up to date. I cannot tether my 3Gs (5.1.1) via USB anymore. The Bluetooth works, but USB isn't even on the list of available internet connections. I have the personal hotspot turned on. I know I could update my phone, but it doesn't have any additional features for my 3Gs, and it slowed quite a bit when I went to 5.0. Any ideas?
