IMessage not working on iPhone 4s?

I'm connected to the internet and everything. All the apps that require internet works perfectly fine and the Wi-Fi at home is full bars and is working perfectly fine… However, I can't use iMessage. It stays green when it's usually blue for the people that I text. I tried restarting the phone and router and that didn't work. I tried turning iMessage off then on again and I tried disconnecting and reconnecting the Wi-Fi on my phone but nothing seems to be working… It was fine until I changed the password on my Wi-Fi but I added everything back to my phone? What is the problem here? How can I fix it?

And my phone is iOS 6

Added (1). IMessage is on and both me and the other person have iMessage and we're both connected to the internet… O.o

Is 16g capacity for iPhone 5 enough?

I'm choosing iPhone 5 because I'll start working and I feel the need of having a single device where you I can do everything.

Music: I'm a music person, so I'll be importing lots of songs (but not too much)

Videos: Not really a movie person, so I don't think I'll be importing videos.

Picture: I usually transfer my photos to my laptop.

Apps/games: I only download twitter, facebook and instagram. Games, not too much as well. About 3 games are enough, when I don't like it anymore I usually delete it.

Others: messages, contacts and etc. I'm not really sure, can you please tell me?

I used to own a 32gb itouch and I only used about 10gb of it.
So umm. What do you think?

Debating on which phone to get iphone5 or GalaxyS4?

I've been with Blackberry for 8-Years and at this point I got tired of it simply b/c the apps SUCKS! I did get the iphone 5 which came out on Tmobile but only had it for a week b/c the camera was defective so went back to my BB, they said to exchange for another one but was afraid it would happen again.I'm trying to decide which phone to get but don't know which one… I mean I love taking pictures and recording videos… With the BB i loved it how I can silence my phone but still have important ppl to still ring on my phone or txt. Not into big phone's, I've been so use to the 9900 BB that I'm afraid of using touchscreen for texting, also I like it how my BB will notify a red light whenever I have a notification. So can you help point out the difference?
