FB contact linking

[starscream]

Anyone know if there is an app that will go through and auto link duplicate Facebook synced contacts?

I have a few hundred contacts in my phone and going through and linking the FB contact to the corresponding phone contact gets very tedious...

also if there is any way to make the contacts+FB contact sync to google account so that I wouldn't have to re link every time I wipe would be neat-o thanks for any help
