Restoring iPhone's voice memos-how to?

I recently synced my iPhone to another computer's iTunes library. My 'include voice memos' tab was NOT selected, and so when they said they'll erase, I thought that voice memos would NOT be included.

However, as you can probably tell, it was completely erased. Now I'm frantic to get them all back, because some things I really need were in there.

Anyone know how?

You said 'another computer'. That means they should still be on the old computer's iTunes unless you've erased them there. Sync when you can they should be there. Best luck.
