iOS 8

Holdouts with iOS 7 installed on their iOS 8 compatible devices now account for just 33 percent of total users. Apple metrics collected on the App Store point to a slowdown in iOS 8 installations, which initially soared in the early days after release. Still, the number of iOS 8 adpotions continues to tick upward.

The total number of iOS compatible devices running iOS 8 currently stands at 63 percent. This leaves only four percent of newer hardware running iOS 6 and earlier firmware. The jump from iOS 6 to iOS 7 was a more dramatic redesign, with users installing the update at a much faster clip.

Some might say that privacy is nonexistent in the digital age, however Apple may beg to differ. The iPhone and iOS 8 provide many options to limit sharing and ostensibly increase privacy on these mobile devices. Privacy settings are a matter of personal preference, and making sure the Settings are configured to your liking will prevent any surprises.

Those who are not concerned about location or data sharing will find the default iOS 8 settings work fine. Others will want to look at these must-have privacy settings for iOS 8 to determine what makes them comfortable. Arguably the most often used and most intrusive technology on the iPhone involves location sharing, thanks to built-in GPS. So accordingly the list of top 10 privacy settings for the iPhone and iOS 8 starts here:

Some iOS 8 users have reported Wi-Fi problems such as slow speeds and other performance issues. Developer Mario Ciabarra suspects the Wi-Fi inconsistencies are because Apple is "using Bonjour over AWDL" and "constraints" of the Wi-Fi hardware make this difficult.

The good news for those with jailbroken iOS 8 devices is Mario has released a tweak called WiFried to solve the problem. Once installed, WiFried provides a toggle in Control Center AirDrop settings. The toggle will disable AWDL (Apple Wireless Direct Link) support, allegedly improving Wi-Fi performance. Note that while AWDL is disabled, AirDrop will not be available.

There are many ways to add icons to the iOS 8 dock, but the tweak betterFiveIconDock keeps things simple. The iPhone 6 and iPhone 6 Plus have more spacious displays, so this tweak takes advantage of the extra room on these two devices.

Once installed, a fifth app icon can be dragged and added directly to the dock. Going back to four icons means simply dragging the extra icon back onto the main home screen. The best part is what happens when the iPhone 6 Plus is rotated into landscape mode.
