What isn't my iMessage working?

My iMessage randomly shuts off sometimes and turns into text messages and when I turn it back on, it either doesn't work or it works on some ppl and not others with iPhones. Anything I can do?

Should I go with Sony or Apple?

My family and I have always been PC people, but I've recently been overwhelmed by Apple's advertising. I was wondering which I should get for the start of my university course: an iPhone 5 and a Macbook Pro, or the Sony Xperia Z and a Sony Vaio (or a combination of phone / laptop)?

Why? What are your reasons for your opinion?

Why does Apple release a new iPad and iPhone every year?

I've been a fan of apple for years now but they are starting to upset me, it seems that every year they release a new iPad or iPhone and it is really starting to piss me off. I feel so embarrassed walking around with what seems like an antique first generation iPad when everyone else has the iPad 4. I'm starting to think about getting the newest iPad but I'm afraid that as soon as I get they will release a new one and I'll just end up wasting my money.

Why can't they wait at least 2 years before releasing an updated iPad or iPhone, I understand the business aspect of this but what about customer satisfaction. I don't want to invest $500 in a device only to be left embarrassed a year later when my device is replaced by the newest sleekest model.

Why does apple do this and what are your thoughts about this?

Where to get ios7 for my iphone?

I have an iPhone 5 model md654ll
I'd like the newest beta of it
What's the safest way to get it?
I can't wait haha

But when iOS7 actually releases (do you know the actual release date?) what will happen when I update it and my phone already has IOS7 on it?
