How to take a screenshot with my iPhone with broken lock button on ios 5.1.1?

My iPhone 4 lock button has gotten stuck and I'm unable to take a screen shot. I know that on ios 6 you can get the screen shot option on assistivetouch. Unfortunately i'm on iOS 5.1.1 and I'm not looking to upgrade because I don't want to lose my jailbreak. Is there a jailbreak tweak that can take a screen shot without using the lock button?

How to transfer songs from your new iTunes to your old iPhone?

I recently have a new computer and I'm trying to transfer some songs into my iPhone. So i downloaded the iTunes and the next thing I knew, when I connect my iPhone to my computer, it only charges the battery. It doesn't sync AT All with my new iTunes! I've been seeing a lot of answers to this problem, like I have to de-sync my iPhone or something from my previous computer but I won't be able to do that until a few months later. They also say I could use a third-party and I downloaded some, but it didn't really work (?) maybe I've downloaded the wrong third-party? Is there any suggestion for a third-party? Or if better, any ways in which a third-party is not needed? Sorry for this, I'm not an apple geek. Any help is much appreciated!

Problems with iPhone 5 charger?

Usually my iPhone 5 charger works perfectly well, and last night I fell asleep forgetting to plug my phone in to charge overnight. This morning however I plugged it in (had 20% battery) and the charger and phone didn't recognise each other, thus it didn't start to charge as normal. I've kept trying and sometimes it makes a buzz noise and shows the charge symbol where the battery is as if it's going to charge, but this only lasts for a couple of seconds then it goes off again. This never usually happens and I don't know what to do?

5 star please only just iPhone update?

I have the oldest version and wants to update to IOS 6.1. I can't find the update button thingy at the settings so would it be okay if I update it through iTunes? Will it crash the system? It's jailbreak already and would it be gone? I'm scared to spoil the system cause it's my dad's phone and if it goes wrong I will never have a phone again…

Added (1). IPhone 4 and not IOS*
