The main perk of Starbucks-Square deal

Why the Starbucks and Square partnership matters, the growing concerns over cell phone radiation, and the free app that brings caller ID to your Android phone.

Wednesday's top headlines are served with a low-fat triple shot of mobile news:

You may wonder why it matters that Square partnered with Starbucks . Customers could already pay for coffee by using the Starbucks app and show their phone screen to the barista. And how much time does that really save compared to taking out your wallet?

This deal is all about awareness . Seeing the Square logo in stores will help people get more comfortable with the idea of phones being a wallet replacement. Apple will also be pushing this concept in iOS 6 with the Passbook app that stores info for reward and gift cards.

In time, we could see more advanced ways to pay with Square inside Starbucks. Square already offers a GPS-based mobile payment app that doesn't require showing a phone to the cashier. But Starbucks isn't implementing that just yet.

A government report says we need to test and update the standards of how much cellphone radio frequency we expose ourselves to before it becomes dangerous. The Federal Communications Commission set the exposure limit standards 15 years ago, but that was before we were holding phones to our heads for hours and storing phones in our pockets.

An investigation from China Labor Watch reports that children are being hired to work at the factory that makes Samsung phones and DVD players. Samsung quickly responded with a statement to The Verge, saying that it's sending staff to investigate these claims.

If you use Google docs for creating spreadsheets, there's a new feature called protected ranges that lets you lock down cells to prevent others from editing.

Today we're keeping an eye on the new WhitePages Android app, Current Caller ID. It shows you who is calling, even if that number is not in your address book. It also will display extra info on the caller, such as what was posted on social networks or news events from their area. It might offer more info than you need, but at the least it helps you know if you should pick up or not.
