I have just downloaded TomTom GPS for my iphone 4 and purchased the HD traffic for twelve months but have put the wrong email address and now I can’t use it, and I can’t remember my password. How can I fix it? How do I change my email address? My account has already been credited but I can’t a access the HD traffic? What can I do to access HD traffic for my TomTom on iPhone 4? I would really appreciate your useful information regarding this. Thanks.
