The Signal is a daily column that brings you the five things you need to know in the world of mobile.
There’s a Hack For That: iPhone and iPad users who enjoy a little bit more control over their devices and the software they install will be happy to hear that a jailbreak for the latest 4.3.1 operating system is now available from the iPhone Dev Blog. This jailbreak was made publicly available just 10 days after the official release. The release does not work on the Verizon iPhone or the iPad 2, so the newest hardware is unfortunately left behind for now. If you’re unfamiliar with jailbreaking, it’s probably best to stay away from it. But for those of you who were waiting for the latest installment, here you go. iPhone Dev Blog
Sony’s Sweet Android Tablet: While it seems that Sony has committed to releasing an Android tablet by this summer, with all the rumors surrounding it, it’s not clear what exactly this device will be. The device will definitely be running Honeycomb or Android 3.0 and will hit the U.S. first, but what the design will be and if it’s the fabled Playstation Certified device or not is still up for debate. Sony definitely has its hand in many places, but it really seems like this would dilute the Playstation brand even further. If the Experia and PSP weren’t enough, they now need a tablet in the family line up. Engadget
A Glass a Day: Kevin Rose, founder of Digg, just announced the details of his stealth start-up, now known as Milk. The focus? To solve as many problems as possible on the mobile web. Rose plans on running Milk similar to an incubator, but with the team already assembled. So far, the team stands at five with Rose stating that he wouldn’t expect it to grow over 10 in the next year. It will be interesting to see what they identify as the issues with mobile web and how they approach resolving them. TechCrunch
No More Blocked Calls, For a Price: TrapCall, an app that lets you see who is behind that blocked number, was officially approved for the App Store. The app is free but costs $5 per month for the associated service. To use the app, simply decline the blocked call (double tapping the sleep button) with the TrapCall app open in the background. The call is routed over to their system and you’ll receive a text message with all the call information right away. Sounds pretty convenient, but a pay-per-use business model would probably be more appealing to most consumers. ModMyI
The Funny Side of Android Trojans: Let’s start by saying that any form of malware is terrible and unfortunate, but at least these developers are getting a laugh. Downloading an app for Android isn’t always safe in the market, but it definitely has more risks outside of it. A supposed hacked version of the app Walk and Text was released through additional markets or available through peer-to-peer transfer, but the app didn’t work as many expected. Instead, it texted everyone in their contact book that the person was cheap and tried to pirate an app. Wired
