hi.
which one of these would you recommend for my Fiesta ST for reading the values and other info, and clearing check engine after de-cat installment before I do a real custom re-map:

Is it possible to connect the Bluetooth version to my iphone 3GS maybe (jailbroken)? other than that I don't see advantage for having the Bluetooth version?
the first one listed is v1.5 is that something newer/better maybe?

cheers.
