Thought I would take the plunge and go for the iOS 5 update on my iPad 2, the main thing I was worried about getting wiped as part of the dreaded sync (I started using iTunes on a PC at my old job….).

I found a program for windows called iExplorer, which seemed to bring up the iBooks directory and I could copy and paste all my 48 treasured programming PDFs over to windows in the way you would expect to do by default… except the file names had all been mangled into unreadable names but still the PDFs are intact.

Then I run the update in iTunes…. and what a shock, 45 minutes later its all done and dusted… all my apps still there.. all my iBooks PDFs still there… games with progress still intact… such as asphalt 6 adrenaline….

Bloody delighted… couldn’t have been smoother in the end!
