I have the much commented on problem with my W800i not accessing Mp3 files despite using the sony software D2P. The walkman function has never worked properly since purchase. I now understand from reading some other threads that the problem IS with the original firmware R1N035.
It is a UK phone which I use now in Australia. It is unlocked and re-coded from brown to red36. My question is would flashing it with a EU firmware like W800_R1BC002_MAIN_EU_1_CA_RED36
relock my phone from use in Australia or cause any other issues I should be aware of before trying?
Thanking you in advance..
