So, iOS 7 is out there, and there's a ton of people trying to download it. As such, we're seeing many reports of folks experiencing issues. Truth is, some of it may just be down to Apple's servers being slammed right now, but there's other issues that you can help resolve yourself. So, here's a few handy pointers:
Make sure you have enough free storage on your iPhone, iPad or iPod touch. By enough, you need around 3.4GB available it seems, so if you're running close to the wire then you'll need to either delete some content or update via iTunes instead (iTunes doesn't need to download the update onto your device first, it stages it on your Mac or Windows PC).
Make sure you're running with plenty of battery power left, or make sure you attempt any OTA updates while connected to a power outlet.
Be patient and keep trying - It sounds ridiculous, but a little patience will go a long way.
There's millions upon millions upon millions of people trying to download iOS 7 around the world at the same time. You might see timeouts, you might see it slow to a crawl. If it stops, just start it again and keep trying.
It's not going to be an easy process for some of us, but we'll get there in the end. Doing everything you can to help the process will make it easier for you in the long run.
