My iphone has turned itself off and won't come back on?

I have the iphone 4 8g and I have had it for only a month, it is well looked after and I locked the phone then 3 minutes later I tried to access it and it is off and will not come back on, I think I had received a phone call which could have frozen the phone, does anyone know what this is? The phone was purchased from an 02 store and is on pay as you go.

IPhone 4 home button doesn't always work? Any ideas why?

I have an iPhone 4. I really like it. But, about 1 or 2 times a week the home button stops working. Sometimes I turn the phone off and turn it on and it works. But if this doesn't work, when I plug it in to a power device, the home button will start working again. Does this happen to any of you? Any suggestions why this happens or how to prevent it?

Set up iPhone 5 for Microsoft exchange?

I have never had an iPhone before so this is all fairly new. I have an iPhone 5 and was wondering if it's possible to get my work calendar in the calendar app. Also the work emails would be a bonus. We have Outlook web acess(Owa) which from a bit of research will let me sync with the Microsoft exchange in the mail, contacts, calendar in settings.

I have looked up the exchange details from Owa, in about and I get the following settings.

Obviously I have removed some details to keep them safe, which details do I need as when I go through the setup I have tried many things and simply can't get a connection. Any ideas?

Is there anyway you can stop a bid on eBay?

Okay so, this may sound like a bit stupid, but I didn't read what I was bidding on (I was in such a rush) and instead of bidding on an iPhone 4, I bid on an iPhone 4 box.
Anyway I can cancel the bid?

Why doesn't my iPhone 4S hold a charge?

I got the phone last December around Christmas time. It used to last so long and I would use it All day not charge it at night wake up the next day and still have about 50-60% and that would last me for the whole next day and then some. It has No damage and all my setting to save battery are on. Like turning off Wi-Fi, dimming the screen all the way down, keeping the apps running in the background killed and all that wonderful stuff. Now I will have it charged to 100% and Me just turning the screen on puts it to 98% and if I check facebook for 5 minutes it goes to 88% and if i send texts or pictures it goes down to 69% literally that is my phone's exact patterns. I wake up usually around 7:30am and it is almost dead by 8:30-9. My phone lives on the charger. Why is it doing this can I get it replaced? Please Help! And don't tell me how to save the battery. I'm a master at saving battery because that's All I do with this phone.

How to make my SIM card for my iPhone 3G fit into an iPhone4?

Hi! I have just ordered a iPhone4. Currently i have a iPhone 3G. The problem is that my 2 year contract is not up, but my brothers is. So any way. He gave me his contract, meaning i could go into the store and pretend that his number was mine, and upgrade for a new phone. Our plan was running smoothly until the man said that the iphone 4 and the 3G have different SIM cards. So any way, we put our order in (because they did not have any in the store) This afternoon i'm expecting that they arrive. I looked it up on the internet and they said that i might be able to cut my SIM card (in my 3G) to fit into my new iphone. Anyone know how?

Added (1). I'm aware that they do sell sim card cutters (haha thank you!) but i don't really want to order one. Is there any possible way i can cut it at home with scissors? I'm afraid i'm going to cut it in the wrong place and ruin it.haha
