Well you need an unlock code which don't come cheap.
You wont be forgetting again in a hurry !
This site charges around 35 euros (do it on paypal for safety if it doesn;t worl) for your phone to be unlocked to whatever country / network you use.
Use at your own risk.
There are others but at least this will work

Please re-install the firmware on the device. And do not use passwords again as we all tend to forget them sooner or later.

Since the lock code has already been changed and no longer to be remembered you have to seek a help with a certified cellphone technician that has an application software that unlocks Sony Ericsson phones.
