Ah, no. Because of Sprint's setup, just about any retailer you buy it from (on contract) has to activate it before you leave. However, updates are not included.
On my phone, Titanium defaulted to the internal storage as a save location. I had to manually change the settings to the actual external SD so you may want to check and see if that stuff is still around.
Trial and error is how we all learn to mess with our phones. Even though I studied the forums and knew to install the updates and then factory reset for the most bug-free stock experience, I still forgot to do a nandroid before I made a few mods. So if it comes down to having to put the phone back to stock for another update, I will probably end up having to flash the stock MF9 ROM.
