Upgrade a slow Iphone?

I recently bought an unlocked iphone 3g off of ebay. I use it on Tmobile. It's jailbroken and is running ios4.0. Like many upgraded 3g phones it's really slow. If I upgrade to the new ios4.1 and it goes back to a locked unjailbroken state, how safe and easy would it be to get it unlocked again? Could I do this myself?
