BB Bold :: Lost Recent Contacts And Parts Of Old Contacts

I bought my bold 9900 last november and back then I connected the phone to the computer and switch from the 9700 that i own previously. Since then I never connected the phone to the computer again until yesterday to update the software. In the middle of my first attempt to update there was a crash so I started again but for my surprise after de update has finished and i reinitiate the handset it seems that almost eveything was wiped out, I had to reinstal all the applications and when the phone was on it came the option the contacts from sim to be installed but then i have some contacts missing and part of the info of some of the ones that still there are also missing, the weird thing is the pictures that i had in the phone are all there.... DO you think theres anyway to get the contacts back? SHould I restore from the backup of the 9700 that i did when i bought the new phone?
