Tricks Advanced/Supergeek for iPhone

1. Entering Engineering mode
The iPhone 5 massages its signal bar, to make its reception look better than it really is. Want to know what your reception actually is? You need to use the Engineering mode.  Type *3001#12345#* into the dialler and hit the call button and you’ll enter Field Test mode. This changes the bar-based signal indicator to a “proper” numerical figure. There are also menus to tell you all sorts of other signal information, but most – including us – will be hopelessly lost here.

2. How to Jailbreak your iPhone
In early February 2013, a comprehensive jailbreak for iPhones was released. It’s a program that’ll hack virtually any iOS device running iOS version 6.0-6.1.2. We’ve not tried it yet, but we’re informed it’s dead easy to do and relatively issue-free. To download the jailbreak, check out the evasi0n website. Evasi0n is the team of hackers that made the software. 

3. Best Jailbreaking applications
One of the main reasons to jailbreak your phone is to install the Cydia app store, which gives you access to loads of apps that would never make it onto the App Store proper. These include apps that can make big changes to the way your phone works – the jailbreak gives apps much greater access to the iOS system’s roots. You’re given much greater control over how your phone looks and feels, and can install things like game emulators – which wouldn’t be allowed (in their pure form) on the App Store.

4. How to fix the “sticky Home button” problem
One of the most common problems with ageing iPhones is that their Home buttons start to play up. It’s unlikely that many iPhone 5s have started to suffer from this issue, but give it time and the Home button arthritis will probably kick in. If youe Home button starts becoming unresponsive, there are a few solutions. The most drastic is surgery. You can buy iPhone Home button replacement kits online (iPhone 5 ones don’t seem to be available yet), or you can try the software fix.

Start up any pre-installed app (as in an app that’s there fresh out of the box). Then press the power button until the power-off prompt appears. Next, press and hold the Home button to leave the app. This will recalibrate the Home button. Of course, it’ll only solve the issue if it’s a problem of software rather than hardware.
