Should I Get iPhone 5 from iPhone 4 Unlimited Data?

I have iPhone 4 but I heard iPhone 5 has many bugs and glitches and many people are having the data problem.peoples datas are being used EVEN tho they are on Wi-Fi. And also the maps are buggy.Once they're fixed, should I get iPhone 5 OR should I wait for iPhone 5S to release next year?
I have unlimited data right now but Verizon told me if I want to KEEP my unlimited data then I need to pay full retail price which is ridiculous! By the way, my contract is over. But if you were me,
would you give up on unlimited data to 2GB OR would you wait for iPhone 4S so it would be worth more?

Also, I heard if you update your phone to IOS 6, it will have same features as iPhone 5 and iPhone 5 isn't that much different other than being bigger screen and faster processer with 3 microphones. I do not know what I should do.

If you were ME, which would you choose? Please help!

Added (1). Would you stick to your iPhone 4 unlimited or switch to iPhone 5 2GB? Also would 2GB be enough 4G if I use Facebook, instagram and Twitter often everyday?

Added (2). Please don't say Droid because I'm into Apple.

IPhone receiving other people's texts

So, my family and I all have iPhones. And lately, when I send or receive a text message, my whole family gets the message that I sent, AND the message the person replies with. I even have my iMessages turned off! Yes, we all share the same iTunes account. But we kinda have to (I think) since the phones were all initially setup onto the same account by Verizon.

But that's not all. Here's the kicker: tonight, I even got a text conversation from my friend and his friend; and they're NOT on our account. For example, my friend sent "I'm sorry." And I got that as if he were texting it to me. Then I got another text from a number I don't know saying "for what?"

So, I honestly don't know what to do or what's going on. I can't find a straight- forward answer on the Internet. If someone could help, that'd be amazing!

I HAVE heard that you can just set up each phone on a different iTunes account. But I don't know if that will work since I'm getting texts from people who aren't on my account.
