IMO if you're having issues so early on in the life of the TP2, I would take it back to the store and see what they say. It shouldn't be laggy/unresponsive unless you're running a bunch of apps at the same time. Even the bloatware from Sprint on the stock ROM shouldn't cause that again unless you're running too many apps. Take it to a store and have a tech take a look at it, you're still well within the replacement period to get a new phone and not just a refurb.
