ok thanks.. can any1 tell me Rm-356 code 0577493 is for wat country?
N wen shud i get my firmware update? Am using version v30... n i have never get update problem b4.. v31will b avaliable for my product code? or i'll blike other guy still on v11 n hade never get update?
does changing product code void the warranty?
Just to be sure, do you mean that it would invalidate the warranty to try to pretend that the phone is from a different country in order to get more up-to-date phone software?
