Today, I changed the password of my Gmail account on a PC computer in a public library. Afterwards, I was/am unable to log into my Gmail account to check the messages via SL 10.6.4's Mail client. I have an April 2010 13" MBP. Similarly, I was/am unable to log into my Gmail account via the Mail client on my 16 GB, 3G iPad, or the 32 GB, 3rd Gen iPod Touch. I keep getting the error message that either the user name or the password is wrong! I checked and re-checked, but I did NOT see anything wrong? The funny thing is that I could log into my Gmail account via Safari on ALL three devices, but NOT via the Mail client on the three devices! I am a new Mac user. Could someone please help! Thanks!
