Hi friends! I'm new to this forum - hi to you all I have made the mistake updating my iPad with another computer resulting in loss of >800 important files and therefore I have spend some time now seraching for appropriate tools to undelete the files - without luck. So I'm wondering - why not write the tool myself. I'm a professional programmer on .Net and have been for many yeras. But I'm new in Cocoa and objective c. Never the less I know c/c++ very well. Enough of talk. Can you guys perhaps give me some pointers on where to begin. Perhaps some snippet of code to check out or a book or some other ressource. I have the nessecary development tools at hand - I hope. Also, I wonder, is the OS/FAT of iPad locked in some way since there is almost no tools for this for public download? Just wondering. I have spend weeks searching the web and AppStore without good results. Thanks in advance. Kind regards, Michael, Copenhagen, DK.
