Having on-demand access to the internet is just about as necessary to us as fresh air and running water these days. When we are away from home, we rely on our mobile data plans for our smartphones and tablets, and Wi-Fi hotspots for our notebooks. Sometimes, though, finding a decent Wi-Fi connection can be difficult and inconvenient.

But not if you have the Karma Go 4G LTE Hotspot in your bag. This pocket-sized marvel allows you to take a speedy internet connection with you wherever you go, so you’ll never have to go looking for a slow public hotspot ever again. And thanks to Cult of Android Deals, you can pre-order yours for just $99 for a limited time — but don’t hang around because this deal is ending soon!

Sony’s new Xperia Z3 Compact, the pocket-sized flagship that was announced at IFA 2014 in Berlin last month, is finally on sale in the U.S. Customers can buy the device directly from Sony’s online store — so long as they’re willing to buy the device outright for $529.99.

A Dropbox bug has left a number of users with missing files that may never be recovered. The issue, which affected those who enabled the Selective Sync feature, is now fixed — but Dropbox has conceded that it may not be able to rescue everything that has been lost.

T-Mobile has today become the second U.S. carrier to confirm that it will be offering the Sony Xperia Z3 this month. Unlike Verizon, however — which has its own customized version of the device — T-Mobile will offer the original that was first unveiled at IFA 2014 in Berlin last month.
