I've been using the native email app to access Yahoo email on my Droid running 2.2 for quite a while and occasionally, it will have issues connecting to Yahoo's servers. It might last an hour, or a day, and may go away for weeks before it happens again. The normal error msg I get is 'Username or password incorrect.' And these are both correct if I check. Sometimes it gets fixed if I just go wireless and connect and then back to 3G, but not always. Reboots rarely help as well. Anyone else experience this and have any solutions? Thanks.
