Do I need to unlock my AT&T iPhone 4S to work on H2O Wireless?

So, I have an AT&T iPhone 4S that I want to use with H2O wireless. I went to a store, and they told me I needed to unlock my phone in order to use it with H2O wireless and that it would cost me $50 for them to unlock it. I don't understand because my cousin has been with 2 AT&T iPhones and he's never had to unlock them when he activated them with H2O wireless.So, was the woman at the shop trying to steal my money or do I really need to unlock my AT&T iPhone 4S to work on H2O wireless?

IPhone 5 battery issue (stays on 1% for long time)?

I've bought an iPhone 5 three days ago and i didn't know how to charge it the first time so i searched it on internet and i found that i need to charge it when i get it out of the box. I hope this is right. So i did it. When it was charging i did an update. When the update was done, was my iPhone almost fully charged. After 10 min. It was fully charged.

I currently have OS X 10.5.8 on my mac. For some reason, it won't let me download straight to OS X 10.6.8.In order to download OS X 10.6.8 it says I need to download OS X 10.6. Then, when I go to download OS X 10.6, it says I need to have OS X version 10.6. That's weird right?

The reason I want to download OS X 10.6.8 or higher is so I can get the new version of itunes that is compatible with my iphone 5. I also would like an updated version of OS X that will allow me to use icloud.

Hi! I turned on assistive touch on my iPhone 4 and went into gestures. I didn't really know what it was so I tried to get out of it but ended up with four or five blue rings on the screen and then i just clicked somewhere.

Iphone - Charging / Cheap usb cable?

1) I'm pretty sure its like this with all electronics, but i'm curious, what's the deal with charging iphones? Like is it ok to leave it charging when its on, even if its been at 100%? And what about leaving it charging when its off? Is that ok? Because I heard its not good for the phone or something like that. What can and can't I do for charging it?
2) Where can I find a cheap Lightning Usb Cable for the 5? I need an APPLE cable, not any other brand.
