samsung kies backup to iphone

Hi

i did the unthinkable a few weeks ago and sold my 4s after getting a little bored of it, and swapped it for a galaxy s3. After 2 weeks i deeply regretted it and sold it and bought another 4s again, yeyyyyyyyyyyyy!!!!

I used a program to extract the contacts, sms, videos and photos from the iphone backup and it transfers them to the galaxy. Since getting the galaxy i removed itunes and also the backup files.

Having backed up the galaxy s3 via a program called samsung kies i now want to somehow extract the contents of the kies backup file (.sbu) and transfer it back to iphone.

I hoped there would be a program that could do this as there is for the other way around, (iphone to samsung) but i cant find such a tool.

Any help would be much appreciated
