This week, we're introducing a new editorial series: "This Week in Mobile", an easy way for you to "top up" your weekly knowledge of the industry and keep your finger on the pulse of all the latest news. Let's get started.

New iPhone Colors?

The closer we get to September 10, the more iPhone rumors emerge. The build up has sparked irrational fears, lengthy debates over potentially doctored photos, and more clues about what exactly Apple will be releasing in early September. This week, it's all about color. Many outlets reported that gold  and silver phones will be introduced. The best news? All this speculation will be over in just three weeks.

Paypal Face Verification

While the 007- esque fingerprint scanner rumor on the new iPhone is interesting, the latest news from Paypal is legitimately cool. The payments company invites customers to "leave your wallet at home and pay with you profile picture" and is currently testing a face verification system through the its mobile app.

BBM

There's a lot of soul searching going on over at BlackBerry LTD. This week, the company "accidentally" posted BBM user guides for both iOS & Android signaling that the BBM launch on the new platforms is imminent. This is a big move for the "withering smartphone business", as BBM has for a long time been one of BlackBerry′s strongest features but we have to ask, "Is it too little, too late?".

Voting via Vine

In the future, you'll be happy you kept your eye on Vine. MTV announced fans can vote for the Best Song of the Summer via Instagram, Twitter and, for the first time, Vine, using #hashtags. Power to the apps! Although, I think we all know what the Best Song of the Summer really was. New to the world of Vine? Search for Nicholas Megalis or Ted Travelstead and they will show you the way.

MEGA

A Chinese developer in China told us last year that phones were going to get bigger. His theory? "Asian hands are smaller so, we're already using two hands. Why not make phones bigger?" But this is huge!  The 6.3-inch Galaxy Mega comes out with AT&T today in the U.S.

Shocked

Finally, you can have a stun gun on your mobile phone. Any mobile news we missed? Let us know in the comments!
