I opened a new gmail account, no problems. used for a month. then i copied a doc onto the page, or something, regardless of what i did, now the google people have 'detected unusual activity' and i am locked out of this account until i contact google with my mobile phone number and then they will clear it up. i tried, but being hooked to china mobile, nothing happened. seems looney that only a mobile phone can help this problem. has anyone had a similar incident and how to resolve?
