Here at Fueled, a mobile development company based in New York and London, we are obsessed with everything that happens in mobile, be it rumors of iPhone hardware, subtle Android updates or new apps we love.

Every Friday, we’d like to help you “top up” your weekly knowledge of the mobile industry so you can keep your finger on the pulse.

Blackberry

This week, Blackberry announced that it received $1 billon dollars in investment from a group of institutional investors, including Fairfax Financial Holdings Limited, a firm some speculated would takeover the ailing company. The agreement caused a big shake up in leadership that included the dismissal of Blackberry CEO Thorsten Hein. News of the investment caused Blackberry share prices to drop by 11%. Not much confidence, eh?

$Instagram$

Instagram CEO Kevin Systrom is instagrammin' his way to the bank. Instagram's recently launched sponsored posts are off to a ridiculously strong start. Systrom revealed this week that over 5% of ad views have led to likes, signaling massive potential for investment and growth for the company. An informative Instagram ad round up can be found here.

More Android

Today, AT&T launched the Samsung Galaxy S 4 Zoom (say that 10x fast) and Motorola is set to release the Moto G next week. The Moto G is suspected to be a cheaper version of the Moto X, which is currently priced at $650.

Speaking of Samsung, they're raising a few eyebrows. During the company's "analyst day" in Seoul, plans for the future were discussed to reassure investors that the team is on top of the mobile game. One of its big reveals is a plan to enter the "fonblet" market which is supposed to mean 'phablet'. Doesn't really roll off the tongue though, does it? A great overview of the event can be found here.

Cheers, Apple

Raise your hand if you've cracked your iPhone screen. You're not alone. Apple is reportedly preparing to offer its customers screen repairs for the iPhone 5 and 5C in store and on site. The company will also be able to repair the "volume buttons, vibrating motor, rear-camera and speaker system" on devices on the spot. Fabulous news!

Puk

We have a confession to make: we're addicted to Puk. It's a fun and pretty little game and we appreciate its minimal design. It's a bit like Snood without all the noise.
