Sprint windows mobile 6.5 start up

[saiyen2012]

whats going on everyone? I was having a problem with my win-mo touch pro 2 soft resetting on its own. I hard restored my phone twice. Called sprint and they told me to update to -win-mo 6.5 Now that I've updated i would like to go back to mobile shell 3.5 on my phone. but when i added it. it still shows the win-mo 6.5 start up screen which is taking up ram because its reading both today's screens at once. is their a way for me too disable win-mo 6.5 start up menu so the today screen doesn't pull from both. thanks for the help in advance. if placed in the wrong area sorry, and i did try Google for the answer and searched the forum.
