Iphone 4s help! Keypad locked?

My nephew has been playing around with my phone, and has changed the keypad lock. He tried to get into it again by trying the code he thought it was however he has not been successful. The phone is now disabled for 60 minutes. How can I unlock it? Is there anything I can do or anywhere I can take it to unlock it? I'm in the UK.

MY iPhone will not charge after being charged forever?

Last night, when I got home from basketball practice it was on 2% I played on my phone for the lasting 3 minutes and it shut off. I put it on the charger and about 30 minutes later it still had the Red Charging sign and it wouldn't turn on, I unplugged the charger and used a different wall input thing and the Apple logo came up but it turned on for about 2 seconds then shut off. I llet it sit and I took a nap from like 9 pm to 11:57 pm and it still had the same thing, I then changed the area it was plugged in at and fell back to sleep. I woke up at 1 and it was still the same. I took the usb and plugged it into the computer and let it sit for about 20 minutes then I plugged it back into the wall in the first area it had been in and fell asleep. I woke up at about 6 and checked it, still not right. I THEN left it on the charge until I got home from school, about 15 minutes ago and its the SAME THING. WHAT IS WRONG

EBay error messages and log in issues?

Two days ago I posted an ad on eBay to sell my Xbox 360. I had it put on as an auction. Checked it (on the eBay mobile app for iPhone) yesterday to see if I had any bites and I did. So I went to check it again this morning and I get the following error messages "Shopping cart error Buyer of given Id / name does not exist. Invalid buyer Id. (515)" and "Notifications Invalid user: *my ebay username* (SOA.Mobile.Request.1)" I can't log back into my eBay and I don't know how or what to do.

None of my devices will connect to my home wi-fi but my family's work fine?

So it started when I was using my laptop at home and the wireless connection suddenly became "limited"
(I use windows 8). My phone won't work either. I used "forget network" for both of my devices and started anew, but nothing, still "limited". My family's devices are just fine, it won't connect as long as the device is mine apparently…
It's an iPhone the phone I'm using.
