I had to get a new LG Optimus-T after four months of use as I was given a lemon. At least on the old phone my gmail account worked well. On this phone EVERY time I try to input my primary gmail account user name/password, it tells me this is incorrect. The user name and password work perfectly fine on my laptop. I have changed the password 3 times and it still works fine on the laptop but nadda on the Android. I have also done a factory reset twice. And I have removed the battery and restarted the Android. I was able to set up a secondary gmail account BTW. However, the primary gmail account is what is linked to my google plus, google docs, greader, contacts, primary business email, tasks and calendar. So I need to have this email account operative on my Android or the phone is essentially useless. Any advice is helpful - Tmobile said they can't help me because this is a Google Issue and there's no customer service contact info for Google. Hence, I'm stuck.
