Few years ago i had create the google account 'uzee2001', just for the sake of using youtube, igoogle and i need a login for my android phone. Back then i didnt care which username i got. NOW - i have created a new google account 'uzee85'. this is the username i always wanted and got now. I have moved most of my google products/services to this new account. Only one thing left is to change the google account on my phone from the old to the new. If i do this, will their be any risks/repercussions or data problems or anything i have to watchout for?
