When I created mi SonyEricsson Sync account into my Xperia X10i, a "random account" was provided to me. Later I received an email with my "login information" to Sync. Then I changed my login and my password to Sync my phone to SonyEricsson and It does not Sync at all. Now I lost the initial login information and I can not find the older one.
Anybody can help me with this?
try to log in to your sony ericsson account online, and verify that you have the correct email/username and password, and when you try to log in through your X10 make sure if you use a or q as part of your password that you press them since the X10 has an issue with those keys.
I would recomend that you sync with Gmail/google rather than Sony Ericsson, if you do decide to sync with Google then you can do this
You could clear out the data in Settings>Applications>Manage Applications, then press Menu hardware button and Filter>All - scroll down to find Sony Ericsson Sync. This should remove your account and you can than re-enter the correct information that you know logs you in on line.
That said, I do prefer Google sync personally!
