Is it necessary to downgrade OS?

[intoflatlines]

I am going to exchange my 8900 for a new one tomorrow (hopefully with no screen wave issue). I am running a .152/.133 hybrid. Should I downgrade the OS to .114 before I return it or does it not matter?

I dont kno about Tmo, but with vzw, if the original os isnt in the phone it voids the warranty. Just as a precaution, i would put the original os that is current with tmo for ur phone in case they decide to ck...that would suk if they say "sorry wrong software-voided the warranty". Thats wat i would do. good luck
