Default Vibrant unable to login Gmail

Anyone ever have their Vibrant error message, that the phone couldn't connect to their Gmail account before? To fix this problem, I have too restart my phone for it too work, but today it took me a couple try for it too work. When they have this Error, there is no 3G or Network. Had this phone for 12 days, and it's my 4 time that it have happen to me.
