How to activate my iPhone 3GS? - 1

I already have an iPhone 3GS from AT&T but got a different one from a friend. The activation can't be completed. I took it to the Apple and AT&T store and they said it has to be unlocked because it's not even showing up in the database because it's from a different country? I put my SIM card in & it says no service, I just want to know how I can get this phone to work!

My iPhone 5 doesn't charge but usb works?

So heres the details on my problem.
When I plug in my iPhone to an outlet or my computer, it shows the little lightning bolt that says its charging, but it doesn't charge no matter how long i keep it plugged in.(and i have no apps running so there's no way that thats draining my battery). The usb does work because I was able to put in music with it. I haven't dropped it in water for the battery to be damaged either. I was wondoring if anyone out there had the same problem with their iphone and know a way to fix it. I already did a full factory reset on it and it fixed two other problems i had with my phone, but it didn't fix the charging problem. I'm not looking for someone to tell me to take it to apple, because I know and already have an appointment in a few days, but would like to know if there's a way to fix it alone.

Laptop can't connect with wi-fi?

I've always used this "plug-in" internet broadband (looks like a usb flash drive) for my laptop in university but now that i'm back at home, i can't connect my laptop to our Wi-Fi. Our network doesn't appear on the list of available Wi-Fi connections and i'm afraid it can't connect to any other Wi-Fi connections as well. When i open the list of available networks, it only shows the "portable broadvand" even if i haven't plugged it in. I tried unistalling it too and still our Wi-Fi network doesn't show up. My laptop has recently been reformatted and i've read somewhere about this "Wi-Fi adapter"? Could this be my problem? And how would i know if i have it? And if i would be able to download it for free? Also, if anyone might suggest the "Wi-Fi button" in my laptop, no, my laptop don't have it.

I know that my laptop is the problem since my ipad and iphone can connect properly with our network. Please be patient with me for i have very limited knowledge with laptops, Wi-Fi and other techie stuffs. Lol basic instructions/explanations are appreciated!

Thank you!

Added (1). Sunny: i tried it already but still the same

Added (2). I don't quite get what pj is trying to say:/ as i've said i have limited knowledge with techie terminologies.sorry! Iwant to know why my laptop can't identify Wi-Fi connections

Pacman, so do you think that my problem is the Wi-Fi adapter?

Hope you guys can clarify and help me out with this. Thanks!

Added (3). Ah nvm! Figured it out!

Facebook app won't re-install on iPhone?

I un-installed my Facebook app from my iPhone because it wouldn't update. I additionally deleted it off iTunes then re-downloaded it onto iTunes. The problem is that when I'm on the app sections off my phone on iTunes, I click install on the app then apply changes, but it doesn't want to install at all. What do I do?
