Are you SERO?
Did you get the tp2 for free?
If you answered no to these questions, I probably would take the phone back and see what else is out there.
Not bashing the TP2, but it took some heavy modding to get it fast and smooth. It was the last of a generation and everything coming out now is killing it specs wise.
If you answered yes to those, and want to run stock, I would flash it back to winmo 6.1 stock and use the cleanup cab found here:

use the first cab listed at the bottom of the first post.
It was the only way the stock ROM ran smooth for me.
If you don't want to go backwards, then flashing customs is going to more rewarding, especially for Sprint since almost all the chefs have sprint.
