For those looking to install the new beta, BGR is reporting that there is a way for you to install the software preview without having an Apple developer account. This is possible through a loophole apparently discovered by BestTechInfo, though BGR warns any non-developers looking to install iOS 8 beta 4 on an iOS device that doing so without a developer account can "cause serious problems for your iPhone or iPad."

They also go on to state that "even if things go well [after installing the new beta], there is no guarantee that you'll be able to update to future beta in the coming weeks."

BGR actually goes so far as to strongly advise against "anyone who is not a developer installing any IOS beta." That being said, here's a video that will show you exactly how to do just that for iOS 8 beta 4.

Also: Should you install the new beta and realise you've made a serious mistake, BGR has you covered with this guide on how to roll your device back to iOS 7.1. Have fun.
