FaceTime over cellular from AT&T will only be available to Mobile Share customers: Customers who stay on a grandfathered unlimited plan or a tiered plan will be limited to using FaceTime over a WiFi connection.  (Via TUAW – The Unofficial Apple Weblog) Not to be a jerk, or anything. But duh. You really thought AT&T was going to allow unlimited free long-distance video calls over their network? I’ve been telling people for years that holding on to an old grandfathered unlimited plan was a waste of…

Infographic: 4G LTE speeds, Verizon vs. AT&T: The infographic below shows each carrier’s average LTE speed in the cities we tested where both LTE services are offered. The cities are ranked according to a composite score of AT&T and Verizon LTE download speed. (Via Tech Hive) The problem with average speeds in tests like this is that they mean almost nothing compared to your real-world performance.

Customers will be able to check their usage with an online tool, and get notifications when they reach 65 percent, 90 percent and 100 percent of their monthly rates. via [engadget.com](http://www.engadget.com/2011/03/13/atandt-will-cap-dsl-u-verse-internet-and-impose-overage-fees/)This impacts two percent of customers…

There’s something very curious about the 200MB Data Plus plan. That number, 200MB, wasn’t chosen randomly. Now that I’ve been reading all these bloggers out there (like my friend, Webomatica) posting their usage over the past six months, I’m noticing a pattern.
