Shoppers who did not have the foresight to pre-order a PlayStation 4 and Xbox One may be left out in the cold this upcoming holiday season. Both the PS4 and Xbox One have already sold more than a million consoles worldwide, making stock impossible to find. However, some savvy holiday shoppers have been able to nab a next-generation console using the whohas.it iOS app.

The whohas.it app allows users to receive free mobile notifications, emails and desktop alarms when out of stock products like the PS4 and Xbox become available for sale through any retailer. The app is simple to use: Just download it for free from the Apple App Store and create a free account. Navigate to "Search" and locate the item(s) you're looking for then tap the "Follow" button. You can then choose to receive "Web Alerts," "Email Alerts," "Mobile Alerts, or all three. The app will then alert you when the item you're following becomes available for purchase or pre-order.

One of the great new iOS 7 features on the iPhone 5s is burst mode. iPhone photographers can snap up to 10 frames per second if they're sporting the latest Apple hardware. Now there's a jailbreak tweak that brings some of this burst mode functionality to devices running iOS 6.1.2 or earlier.

BurstMode is a free tweak that adds some useful functions to the stock Camera app. Once installed, several settings provide options for how BurstMode behaves when taking a photo. Of course, the BurstMode tweak can be completely disabled thanks to a toggle. When enabled, holding down the shutter release button or volume button will snap continuous pictures.

Frequent Do Not Disturb users might be wondering how they can gain more control over the feature. Luckily for those running iOS 6.1.2 or earlier the DNDPro jailbreak tweak does the trick. Installing this free package will add two new options to the stock Do Not Disturb settings. These same items will also appear in their own location under Settings -> DND Pro.

DNDPro revolves around enabling Do Not Disturb mode while using specific apps. This means that notifications can be turned off automatically while an application is in use on the device. Closing the app will turn Do Not Disturb mode off again, resuming normal alerts and phone calls.

When it comes to quickly accessing iOS Settings, there are many options available on a jailbroken device. Toggles and other shortcuts can make burrowing through multiple Settings menus to change one item a thing of the past. MultiShortcut adds another free option for those looking to change settings in a flash.

Once installed, MultiShortcut adds 32 instant shortcuts right to the iOS home screen. How is this accomplished? Touch and hold the Settings icon and the list of shortcuts appears. Scroll to the desired item and select to instantly access this portion of Settings. There's also a Close button to dismiss the menu and skip entering Settings if needed.

Does your jailbroken iPhone have a long list of alarms set up in the Clock app? Sometimes things can get disorganized, with some alarms on and others off. Scrolling through this list is easy enough, but the AlarmControl tweak makes things even easier. All alarms can be toggled immediately with just one button at the top of the screen.

Once installed, AlarmControl will add this Toggle Alarms button to the Clock app, right next to the add new alarm (+) button. Tap the toggle once, and all alarms are off. Tap it again, and every alarm will be turned on, it's that simple. Imagine going on vacation and touching a single button to keep your iOS alarm clock silent for the entire trip.
