Singapore still show no update. Its available for Malaysia lumia 800

so, does the update wipe out everything?

i don't know if anyone have posted about this before.

i just traded my nexus s with lumia 800 few days ago. had setup the phone with malaysia account, i found out that the marketplace in in malay and lacking xbox support. so i try to find a way to change to singapore account but most advise need me to do reset on my phone which i consider the last resort since i already bought a few apps.

so what i did was: Change my Xbox Account Region to singapore and update my billing info. just fill in the form and at the post code part, just put legit singapore post code. restart the phone (not sure if this is necessary) then after a while i get the marketplace in english and access to most apps that wasn't available before.

hope this helps for those in the same boat with me. i spend most of my day digging through google (which only shows old thread stating need to reset) until i found this solution 

for starter, we should have 2 account. 1st; windoes live id which used for activation, 2nd; xbox account for market n billing. I assume u already have windows live id, so for xbox account just go to xbox.com and sign in using the same windows live id. In account, update your billing information as stated on previous post, which the main purpose is to set your region as singapore using valid singapore post code. The rest of the information doesn't matter mostly.

Someone please correct me if i'm wrong :-)
