AT&T may want to think twice about the name for its prepaid GoPhone service -- it's not just for phones anymore. You can now bring your own tablet to the no-contract offering, with pricing similar to what we've seen on the carrier before. Spending $15 per month will get you a (frankly paltry) 250MB of data, while bumping that up to $30 or $50 will get you a far healthier 3GB or 5GB, respectively. Should you need more, you'll pay for it in $10 blocks that give you 100MB, 500MB or 1GB, depending on the existing plan.
