i have xperia x10
First back up ur phone numbers
now go on ur pc and log on to ur google mail account
once logged on goto settings
now goto accounts and import
where it says send mail as, switch to @gmail.com (you need to switch ur address to gmail or googlemail )
once you have changed your mail address log out
on your phone goto settings, applications,manage applications and you need to clear cache on the following
google talk, google mail, google apps, market, download manager
turn phone off and on again and goto google talk and log on ur new google address(@gmail.com) once you have done this try downloading a app from market( if you have apps downloading pending cancel and restart.
this is what i did and it worked for me, no factory reset needed
hope it works good luck
