Bit of a unique situation. Have MacMini with 3.0 sdk, iTunes 22.214.171.124 and iPhone and iTouch with 3.0 installed as well. Everything there works harmoniously. Also have a pc running latest iTunes. Harmony as well between all devices. Here's where it gets complicated: I have a Powerbook G4. Seeing as I can't run the sdk on this set up I dragged the .dmg files over for the new iTunes and iPhone (same way I got this on my pc). I updated iTunes to 126.96.36.199. From that point forward that computer no longer recognizes either the iPhone or the iTouch when plugged in. They don't even charge. What happened? How can I fix it? (One possible related issue, not sure: When intending to install iTunes 188.8.131.52 on my G4 I accidentally ran the iPhone 3.0 .dmg. The open animation ran but nothing happened after that.) Hints? Tips? Suggestions? Very much appreciated - Wiscal.
