United Online's NetZero business is making headlines this week with a free 4G connectivity deal that isn't as free as it looks.

Earlier this month, Apple's marketing department pitched iPad 2 as a great gift for Valentine's Day. But with the iPad 3 a mere three weeks from release, we have to call foul. A dozen roses may not last that long, but no one's buying a $499 flower arrangement.

Too many of us aren't being smart with our smartphone data consumption, and the results are clear: Clogged wireless broadband networks, dropped connections, rising prices, and worst of all, expensive data bills. But Onavo wants to help us cut, compress, and otherwise tame our wireless use -- and it won't hurt a bit.

Apple shares are trading near their all-time high of $422.86, but most analysts expect them to go much higher. Forty-six analysts tracked by Thomson/First Call have a median price target of $500 -- an approximately 20% rise -- and the most optimistic among them forecasts the stock will hit $666 -- about 60% higher than it trades now.

Let's go over five of them.

Distracted driving has been a growing problem since cellphones came into wide use. Now, new research shows that among the young, the proliferation of mobile devices and the explosion of apps they have spawned have made the problem much worse.

AT&T will spread its 4G LTE network into a large number of U.S. cities this year, a move that puts it into direct competition with Sprint-Nextel's Wimax 4G product and LTE technology deployed by Verizon Wireless. But will its investment in faster wireless pay off?

Regulators have begun to take a long, hard look at whether the AT&T buyout of T-Mobile would create a quasi-monopoly in the American cellular carrier industry. If those antitrust concerns sink the deal, AT&T could be in real trouble, because cellular is its only clear hope for growth.

Apple's earnings per share nearly doubled last quarter, and its performance the previous quarter was almost just as good. But Apple's shares are only up 11% in the last six months, trailing the Nasdaq. Here's why the stock could be set to take off.
