I'm thinking of possibly doing the above to my iPhone.
Is there a way of changing back in the future so that the phone is not jailbroken? (I'm guessing once it's unlocked, it unlocked and there is no going back on it)

Yes there is. Everything is 100% reversible. Just hit Restore in iTunes and everything is gone-gone.
Not true actually, depending on boot loaders versions, you can't reverse a baseband update.
