Help FB & my HTV Hero

[fresh crayons]

My son gave me his HTV Hero to use until I can upgrade in November. I am new to smart phones -- and I noticed I have two FB applications in my phone (FB Version 712 & Facebook for HTC Sense). Which one is the correct application for my phone?

They both are. It really comes down to personal preference for which one you use.
