Looks like AT&T has been tweaking its data packages again, trying to find a way to better compete with the likes of the Sprint, T-Mobile, and VZW no doubt. The revised data plans will go into affect on January 22, and they look a little something like this:

• Data Plus 300MB: $20 for 300MB
• Data Pro 3GB: $30 for 3GB
• Data Pro 5GB: $50 for 5GB, with mobile hotspot / tethering

So, how does that compare to Ma Bell's current data rates?
