iMessage is not working for iPhone users, according to popular posts from Twitter users.

iMessage is a feature of the iPhone where users can send messages quicker and faster than text messages.

iPhone users can only send iMessages to other iPhone users, and they show up in blue blurbs. If someone has another type of phone, or if iMessage is not working, as has been reported Thursday, then the message is sent as a regular text and appears in green.

People can also see when the user and sender is typing, in addition to seeing if someone has read the message that was sent.

iMessage also shows a character count and can add a headline to a message.

For those who can’t stand pesky group messages, that part of iMessage can be turned off; in fact, all of those are optional features that can be turned off.

Some popular tweets iPhone users posted to Twitter regarding “My iMessage” being down were:

@tyleroakley tweeted, “My iMessage is down... which means I have to text my friends like I'm some common peasant. Ugh. Life is so hard.”

@IAmJossh said, “I hate when my iMessage isn't working. Because that means my text are going to be green & green text are ugly.”

JaackMaate shared, “My iMessage must be from Liverpool. Because it's refusing to work.”

@AinTime4That wrote, “My iMessage isn't working? Ain't nobody got time for that”

@imakeit_rayne posted, If my iMessage sends as a text, I will keep sending it until it turns blue.”

@StevenAmiri asked, “My iMessage is green instead of blue. Does that mean I’m pregnant?”

It’s unclear why iMessage isn’t currently working, but The Verge reported that it was working for OS X MacBooks.

As iMessage is down it seems that Apple CEO Tim Cook and Co. are more concerned with talking about Microsoft’s tablet, the Surface.

During Apple's fourth fiscal quarter earnings report on Thursday afternoon, Cook said, according to GeekWire: "I haven't personally played with a Surface yet, but what we're reading about is that it's a fairly compromised, confusing product. And so I think one of the toughest things you do is make hard tradeoffs and decide what a product should be, and we've done that with iPad. I suppose you could design a car that flies and floats, but I don't think it would do all of those things very well. I think people when they look at the offerings will really want an iPad."
