Can I put a 9780 motherboard in a 9700?

Hi, My Friends Blackberry Has the wsod, He gave it to me so i get it fixed as i Have quite a lot of knowledge on this as i fix laptops and sometimes Phones :D I Tried Everything... Now just tired of it so thought of getting a broken 9780 to swap the MB, Just wondering is there something i should know of? Any Differences about them?

No bro it won't work. I remember I had a BlackBerry 9700 way back in a day. The phone wouldn't turn on whe ln I installed the 9780 housing. So don't take any risk. Iam sure it will not work...
