IPhone 4- Is there any way to retrieve just the recently added contacts?

I used to use same laptop with my brothers. The problem was when synchronizing to the iTunes app, all the contacts of my brothers' synch on my phone. You may try synchronizing your phone to the old iTunes.

another solution= you may have backed up on iCloud. Try restoring from that.
