I got my ** year old mother a phone. She put in her email address and then forgot her password. so I thought the best thing to do was take it to the Sprint store and have them help. They said reset the phone. but didnt tell me it would still ask for the *st sync'd email which of course we could not get in.*I went to sprint again, different store, and they "contacted you google" and where supposed have reset it, so that my name and email was in the phone. but I had to wait ** hours to get in. After that time, it still would not let me. I have been attempting various ways to get in to no advail.*The account my Mother has. UtaB*****@***.com also has the wrong phone number with it, but has the correct recover email *****@***.com, but it still will not let me in. The phone is registered with Sprint under my account. It's a family plan.*Please let me into my mothers email address of *****@***.com or let me unsync this email address so we can start new.*Thank-you very much. I look forward to your prompt response.
