I am looking into the android platform and currently have a nokia N95 with a family plan from ATT, with family messaging I have a $10 month unlimited data plan. Just wondering if I upgrade my phone w/ATT if I will lose my $10 plan so I am thinking I need to buy an unlocked phone and just use my current sim in it. I was thinking Vibrant but hear only EDGE network works on those. I did try my sim in an unlocked Vibrant and had 3G for a short time verified with speedtest but then shortly it switched back to EDGE so is there hope with the Vibrant and 3G or what was going on???
