I THINK I BRICKED MY IPHONE

So a couple months ago i updated to ios7 before the release date and everythings been working absolutely fine since. Just now, my phone came up with a message saying "activation required" so i tried to activate it and it came up with a message saying "this device is not registered as a part of the iphone developer program. If you are a member of the iphone developer program register your device in the iphone developer program portal at http://developer.apple.com/iphone" and i can't do anything with my phone now. Please Help did i brick my phone? How to i get out of this!

Today my iPad and iPhone 5 say activation required?

Just now, my iPad locked and had a message saying Activation required, so I went along with it and unlocked my ipad and it said to choose a Wi-Fi network (which was already chosen), so I clicked next and then it said Activation Error. Your device is not registered as part of the iPad Apple Developer Program, etc. Then a few seconds later, my iPhone locks as well and again, the same thing happens. They are both running iOS 7.By the way I don't know if this matters or not, but I downloaded iOS 7 from the internet a month before it was released to the public and it worked just fine. But I researched it and apparently this is happening to some other people who got iOS 7 the day it came out. So what do I do?
Also, when I hooked my iPad up to the computer and tried to back it up and sync it, it said it didn't work (this never happened before, it even worked after I downloaded iOS 7, it just isn't working today).

How to download a previous iOS software?

So I have an iPhone 4, and I downloaded iOS 7 and it took up so much space, so I tried deleting apps, and still didn't have enough. I had to end up getting rid of my music, which I realized was not a good trade off! How do I download a previous iOS software? Like iOS 6.1.3? Any information would be helpful. I'm kind of technology impaired, so if you could break it down step by step that would be awesome. Thanks!

Added (1). If I can't download a previous version, is there a way to create more space on my phone?

Audio recording app for iPhone?

I need an app to run on my iPhone that can record audio - I don't necessarily need it to record video too. But I do need to be able to use the audio recordings on Adobe Premiere Pro to layer over other videos I have already shoot. Any suggestions?

How much is it to upgrade to an iPhone 4s on ATT?

I want to upgrade to an iPhone 4s since it is now free following the iPhone 5s and 5c release. How much would it cost to upgrade? I think it is 150$ but I want to be sure. IT WILL GET A CONTRACT.

How does Apple's glitches compare with Obamacare's glitches?

Obama said when Apple released it's new software they had a few glitches too.
One week after IOS 7 was released it was running on 60% of iPhones and IPads.
The day the iPhone 5s went on sale you could log on to Apple.com and order one.

How does that compare to:

Transferring contacts from iPhone to Android?

My iPhone 5 broke a couple of days ago and instead of paying to get it fixed (the warranty was voided) I decided to get an LG Optimus g Pro, I backed up my iPhone a couple of days before it broke and I was wondering if I could get my contacts off of the backup and on to my Android without having to pay for something

Will an unlocked 32gb iPhone 5 work with Straight Talk?

Right now I'm currently on AT&T GoPhone $25 Unlimited messaging w/ 250 calling minutes plan. My phone is an AT&T Fusion. Around Christmastime, I'm hoping to upgrade to an iPhone 5, but I do not want to be stuck with a two year contract. So I've done some research and saw that Straight Talk has an Unlimited Text, Calling, and Data plan for only $45 a month, which I can afford. Then I looked at the prices of their iPhone 5's and I about fell over, $700! So I decided I would buy an unlocked 32gb iPhone 5 (I haven't bought it yet, but I've seen some practical prices) on eBay, and then buy the Straight talk sim card to put in it. But as I looked up ways to do this, I saw that some people say you can, some say you can't. So here's my questions:

Are unlocked iPhone 5's from eBay compatible with Straight Talk? If so, do they need to be compatible with T-Mobile, Verizon, At&t, or any other company?

Could I use my old sim card and phone number from my old AT&T phone and put them in my unlocked iPhone 5?

How would I know if the unlocked iPhone was a GSA or CDMA? Should I get a certain one for it to be compatible for Straight Talk? If so, which one?

Would I ever be able to use the same iPhone on another phone company (if I ever decided to switch)?

Anyone who has done this, was it simple or complicated? How's Straight Talk's reception, and data speed on iPhone's? Is Straight Talk a reliable company?

Please be specific as possible, I'm very well confused!
