I have just bought an S2 on T-Mobile and have been trying to sync it with my Gmail account so I can get my emails straight to my phone and be able access The Market to download Android apps, but I am not being able to do so. I made this Gmail account quite some time ago and never used it with Android before if that makes any difference. It worked fine on my iPhone though. I have another relatively new Gmail account and when I try to sync my S2 with that account, it goes through successfully and downloads all my emails without a problem. This is the message that I get when I try to add my Gmail account to my S2: "The attempt to sign in failed due to an invalid username, password, or incorrect settings. Please check your username, password, and settings on the web, and try again. (301)" Please could anybody help me.
