Apple is set to make 5 billion dollars less this quarter than it previously expected. That’s a pretty big deal, and it’s down to two major things. One was an “economic weakness in some emerging markets.” The other was that Apple said it sold “fewer iPhone upgrades than we had anticipated.”

That second one is very interesting. Why aren’t people upgrading? There are two possibilities. One is that they’re switching to Android. The other is that people are holding onto their old iPhones for much longer. Why’s that?

The next iPhone could be the most expensive smartphone Apple’s ever made, but according to some analysts, carriers might step in so customers’ wallets aren’t hit quite so hard.

AT&T customers soon won’t have to worry about going over their monthly data limit, thanks to a new set of plans the carrier is rolling out nationwide later this month.

Instead of cutting your data off once you go over, the new Mobile Share Advantage plans simply throttle your speeds down to a maximum of 128 kbps, making the carrier more competitive with the likes of T-Mobile.

Verizon will soon start charging a $20 fee for anyone upgrading their smartphone with pretty much no loopholes to get out of it. Yes, a carrier is introducing a new fee without much explanation and customers are forced to deal with it. Shocking, I know. The new fee goes into effect April 4.

The war between mobile carriers in the U.S. continues to heat up and with the latest battle, it’s personal. Sprint came out with a new ad that directly targets Verizon’s from just a few weeks ago. Using big, colorful balls to symbolize network quality and performance, Sprint claims Verizon’s ad is rubbish and outdated while the yellow network is the true champion.

Some U.S. carriers have historically been more lenient about unlocking phones than others, but starting today they are all mandated to provide unlocking once a customer’s contract is up.

Legislation put in place by the Federal Communications Commission back in 2013 takes full effect today, and carriers must comply with new policies on unlocking.

There’s a really cool feature in today’s new iPads that got zero stage time during the keynote. Apple has built its own SIM card that allows the user to switch between different carriers and plans right from iOS.

Slowly but surely, T-Mobile has been trying to not only become the leader of the prepaid cell phone market, but to totally corner it. It’s latest ultra-simple plan takes that mission even further, making pay-as-you-go as simple as $0.10 per minute or text, flat.

Yesterday, AT&T announced new Mobile Share Value plans that were pitched as making subscriber’s monthly rates cheaper if you already own a smartphone.

It seemed like a pretty honest move. Most carriers bill you a set monthly that includes a fee designed to pay off your smartphone’s full prive over a two year period, which is common knowledge. What isn’t common knowledge is that on most carriers, even if you bring your own smartphone to your contract or fully pay off your device, the carrier will continue to bill you for that smartphone subsidy in perpetuity. It’s super sleazy, so AT&T’s move seemed like a refreshing dose of honesty.

That’s not how T-Mobile sees it, though.

Right now, Apple sells three generations of iPhone. The iPhone 5 is the high-end phone, starting at $199 on contract. The iPhone 4S is the mid-tier device, and costs $99 on contract. Finally, there’s the iPhone 4, which is free on contract.

Come September 10th, though, Apple’s going to change things up with the colorful iPhone 5C, a device that Cupertino has designed from the ground up to be a modern budget iPhone (rather than just a hand-me-down iPhone a couple generations old). So the iPhone 5S will take the high-tier, and the iPhone 5C will take the lower-tier.

What about the mid-tier, though? Evidence suggests it’ll be the iPhone 5.
