KIK What does the S mean on iPhone?

I know S is sent D is delivered and R is read, but usually when you send a message to an iPhone and the device is offline is supposed to appear a faded D. Today I sent a kik message to an iPhone and an S appeared, what does that mean? Isn't the faded D supposed to appear?

Not exactly, I recently read the KIK description about this and this is what it said:
Three dots mean that the app is trying to establish a connection. Your message will change to S as soon as a connection is established. If you see the three dots for an extended period of time, check your data and/or Wi-Fi connection.
! Red exclamation mark means there's an error sending your message. In this case, you'll need to send your message again.
A faded D appears next to messages sent to iPhones and Windows Phones. It means that we've sent the push notification of your message to your friend but they haven't opened the app to receive the message on their phone. Once they open the app, you'll see a solid D.

Basically, S means the iPhone hasn't received the message. If it had received the message but the APP wasn't opened yet then faded D, if the APP is opened but message not read then dark D. And if the message was read then R.
