What can I do about my iPhone 5 problem?

I've had my iPhone 5 since October 2012, basically just after it was released. Just a few months ago, the lock button became very faulty and it can literally take me endless numbers of tries to actually lock my phone, the button just barely works depending on how you press it. I also receive a notification of a text message (my text message sound goes off again) after the already receiving a notification of the text message, every time. They're both really bugging me but I don't know what I can do since I don't have applecare and it's been just over a year since I got my phone. Is there even a point in bringing it into the apple store?

Deleted Kik app, How to tell if someone has deleted it?

I was talking to someone today very briefly and they said they were deleting their kik app. I know they have an Iphone.

On the kik Faq it state's a faded 'D' means that the person has received the message but it is under a push button notification for Iphones and Windows Phones. Meaning they still have the app but haven't check their notifications yet.

I read somewhere that if they deleted their kik "it's a solid faded D" - but i doubt it's true.

My question is how do i know if someone has deleted their kik app by judging the Kik status symbols. I have no communication with this person whatsoever.

Will they receive my message?

Cool gadgets and tech stuff?

What are some cool tech stuff as my mum has no idea what to get me for Christmas and my 18th and I'm a very techy person but I already have an iPhone and a custom build PC.

I'd like a MacBook with my own money put towards it for when I start work but they are so expensive and a tablet isn't much good with having an iPhone already as an iPad is just a bigger version. Windows don't have many apps and android is so old after having a bunch if android phones and a tablet.

So what are some things that would be cool and tech related or even something useful for when I start working as want to work in IT?
