My Sony Ericsson z550i phone lock code is forgotten by me. whats the solution for it.

HI buddy, c if u are the only user then u can try  default phonelock code ie0000 or else renew ur cellphone software .Either u can  do it from  1>any sony ericsson service centre -> ask them to renew the sofware.  2>or else try downloading the sof ware from sony support website or third party websites like brothersoft.com/bitcomet.com etc. this will surely help in solving ur issue.:):) Have a great day!!!!!
