Unlock W200i Orange france for ATT

[TedT-CA]

Hi,

I see you have provided some unlock codes for the W200i. My son just sent a year in paris in school and brought back a Sony Ericsson W200i. He purchased a SIM card from ATT for it now, but I guess it needs to be unlocked. The info is:

MEI# 35735401-7++++++++++++++
Purchased in France
Orange is the provider

Will be use din ATT in California.
Thanks
