A thing to convert iphone 3/4/4s made appliances to be able to use for an iphone 5?

For example I have a speaker that you can plug into a dock made for iPhone 4/4s but I recently got an iPhone 5 and I don't really wanna buy a whole new speaker made specially for an iphone 5 (cause the plug in charger place is different).Is there such thing as where one side i can put it onto the speaker dock and the other side I'll be able to put into an iPhone 5? I've seen one before but i don't know what it's called.

If I unjailbreak my iPhone 5 will Apple fix my lock button?

So I pre-ordered the iPhone 5, and got it on the day it was released. So it's technically still under its 1 year warranty. I jail broke it about 3 months ago, and since then the lock button has stopped working. My boyfriend who got his phone the same day, doesn't work either. Nothing is psychically wrong with it, just doesn't lock/unlock the screen. If I update to ios7, or unjailbreak it, will apple be able to tell it was jail broken at one point? Or will they still fix it?

Can I swap SIM card in iphone 4s into 4?

I just dropped my iphone 4s and the screen/display is no longer working. The rest of the phone works and I was able to back up. I have an old deactivated iphone 4 that I can use. I want to know what steps I need to take to get the 4 up and running (i.e. How to activate). If there's a detailed set of instructions on the web you can point me to that would be great also.

How to make it so my alarm rings through my headphones on my iPhone?

I'm a bit of a heavy sleeper so whenever I set my alarm it normal wakes everyone but me up, which means everyone's grumpy in the morning.

How do I make it so that the alarm rings through the headphones?
I already set it like a minute before to test it and it plays out loud and on the headphones at the same time? How do I set it so that it only goes through the headphones and not the speaker?
