SE W350i Firmware Upgrade

I have a Sony Ericsson W350i which i got unlocked by local shop (orignally locked to Vodaphone) I would like to try and upgrade the firmware on the phone but i have a question if i try and upgrade it will the phone still be unlocked or will it be locked agian after upgrading the firmware?

Thanks in advance.

Not sure about using SEUS, but a normal firmware upgrade using any normal flashing tool like XS++ should work ok without it becoming locked again.
