+1 for a re-flash, even the stock ROM.

My current TP2 is a refurb after the "oil slick" on the original device. When this phone arrived it had issues with certain keyboard keys not functioning properly and random "lock-ups". As my warranty was about to run out, I requested and received another refurb. Before dumping the first refurb, I tried a re-flash of the stock 6.5 ROM. Everything just started working! My assumption is the refurb process involved a faulty flash.

I sent the second refurb back unopened so someone else could have it.

To eliminate lock-ups and greatly increase your battery life (not to mention making the device function more "snappily"), I strongly suggest over-clocking. I never lock-up and the battery lasts almost three days! At 806Mhz, it's almost Snapdragon fast! OK, that's a bit of hyperbole, but it really is a great improvement.

To eliminate the RAM leak, I suggest turning off Sense. As previously suggested any UI (even Titanium or the "stock" Today screen) will improve over-all performance.
