Hye. I am having problem to read iphone 5 64gb storage via lightning cable to PowerBook g4 ubuntu oneiric .. Any advice ? The iPhone 5 run on top of arm processor while PowerBook g4 run PowerPC processor.<br/><br/><br/><br/>my.linkedin.com/pub/yb-tan-sri-dato-ir-adli-a-k-a-dell/44/64b/464/<br/>Sent from Yahoo!
