Sony ericsson A2 Phone unlock free

[kevpc]

many tnx for info. assume i need to install usb flash driver first? however, dont know whether phone should be actaully turned on or not or if a sim card should be in phone or not. hope you can advise further. sorry for my ignorance. just dont want to make a mistake.

well. dont know if what i did is correct but, installed the usb flash driver, then opened the aerix program. connected the cable to the phone, then to pc when indicated. typed the username and password when asked, selected my phone from the list and hit 'unlock'. had no sim card in phone at the time (dont know if i should have or not). still get the Vodafone logo when i close the phone and Vodafone Live link still on main screen. maybe should have done a bit more reading and unbranded the phone before doing the unlock bit. however, have tried a 'tesco' sim card and all appears to be working!! can i still unbrand the phone or will it then become locked again? if so, will it then unlock again? anyone know please?
