Should I update to iOS 7 beta?

I really wanna update to iOS 7 beta 4 on my iPhone 5 and check out all the cool features, but I'm afraid that I'm gonna lose everything (contacts, pictures, apps, music, etc.) and that I have to go back and try to restore everything. Also, I'm not so familiar with iCloud, and I backed up on my computer too, so if there's a way to get all your stuff back onto my iphone 5 on ios 7 like contacts, pictures, apps, music etc. Please tell me!

If I was you I would just wait, because it could be possible that you will lose all your data. IOS 7 is supposed to come out pretty soon anyways, and I think the only way to get IOS 7 beta is kind of illegal in Apple terms.

I would wait until it is released to the public. Cause you could end up bricking your phone and all you would have in the end is a very expensive paperweight.

I've been running it on my 4S. It's totally worth it. The biggest thing you need to be careful about is that Apple will deactivate your device if you attempt to install the beta without first registering your UDID with a developer account through a site like http://www.udid.in/.It's $5, and they literally registered my 4S instantly and I haven't had any problems.

Personally, iOS 7 is just a beta version and may not be stable enough for users to have a comfortable experience. So let's come to a stop when trying to the newest iOS 7 and wait for a better version to come.

But if you like, you can have a try. Be careful in the process, because you may lose data during the update. Backup your data with iTunes, iCloud or other third-party tool before the iOS 7 update if you are going to.

I'm on an iPhone 5 that's non-developer registered. And I'm running iOS 7 b4 just fine.

Here's what you need to do.
Get the relevant IPSW file (build 11A4435d, google it. Check whether you have the A1428 or A1429 iPhone 5.It's on the back panel. A1428 is for AT&T only. A1429 is for Verizon and International)

After downloading the IPSW, run a backup.It'll keep your media (photos included), contacts, text messages, calendar events, settings, etc.

After that, in iTunes, under the Summary tab, hold down Option (Mac) or Shift (Windows) while clicking Check for Updates. You'll then be prompted to select the iOS 7 IPSW file.

Then just run the update. Done.
