I have a sony ericsson K800i on tmobile and need the code to unlock it to any network, does anyone know this code at all

sorry you have to go to a website and get the unlock code (costs money around... £20)

Go To: www.mobileunlocked.co.uk

hope i helped!

you need the specific code for that phone, each code works for only one phone. call t-mobile and tell them that you are traveling overseas for about 2 months and wanna use your phone and they will give you the code most likely over a email in about 2 to 4 days
