Good news and bad news here, folks: the good news is that AT&T will begin offering new data plans with a higher monthly allotment. The bad news is that, once again, it's going to cost you more. The plans, which will offer 300MB of data for $20, 3GB for $30 and 5GB (including mobile hotspot access) for $50, will take effect beginning this Sunday. Are you still on one of the older plans? Fortunately, you're still grandfathered in and won't have to change unless you absolutely want to. But remember that once you move to the new data rate, there's no going back; the only legacy plan sticking around is AT&T's 250MB tablet feature for $15. The change in plans appears to be priced the same as Verizon, though the two higher rate plans on AT&T have an advantage in that it hooks you up with an extra gigabyte of data capacity. The question is, will it be worth paying an additional $5 per month for that extra gig? Oh, and we're still waiting on that shared data plan in the meantime, Ralph.
