I'm a little concerned because not long ago I went to sign into the Live ID we use for the phone, and it said we had been locked out because of suspicious activity on the account. I had to go through the customer service option to get back into the account because the only other option was to send an email to an email address we no longer had access to. We use this account for everything, Phone, Xbox, Zune movie rentals, Hotmail, SkyDrive and so-on, so it was a pain in the ass. Needless to say we have a new password, but I just hope these events aren't related (i.e. someone got into the account and did a remote wipe of the phone).
Is there a log of this stuff anywhere that we can access??
