First Issue: I cannot setup my POP3 (Yahoo) email accounts on the phone. I get an error message that says, "Invalid username and/or password". Since I couldn't get my email the regular way, I decided to try Gmail. I set up the Gmail account and added my two POP3 accounts to it. Everything worked fine for one night. Now my Gmail account is not receiving any new email messages...even if I log on via computer, the Gmail account shows no new mail. What am I doing wrong? It's frustrating to have to use Gmail in the first place.
