My iPhone 3GS keeps randomly turning off?

I have an iPhone 3GS and I'll just be on the Internet or sending a text and it will just randomly turn off. When I start it up again it shows the apple sign for a bit but them just turns off. As soon as I plug it in to a socket though it works. The battery is quite old but the phone has just been updated and reset. Could it just be the battery? If so where do I go to get it changed?

IPhone 5 screen protector coming off?

When I got my iPhone5 they put on my screen protector for me, like professionally I guess, with the glue. At the bottom the little corner around the home button is already coming off and it's really irritating. Could I get it removed and they do it for me? Or should I just like take it off. And if so, how? And will it be okay without a protecting screen, iPhones are like butter.

I'm not able to loginto gmail and facebook in iPhone?

Earlier I was able to log into Gmail and Facebook in my Apple iPhone. But recently I'm not able to use it. It is showing as ID or password incorrect, when I use ID and password correctly. Actually one of my Gmail account which was already added in iPhone is still working in my iPhone. I have not restored anything. I removed and tried, still it is not working. Do you know why is it like that?

Was I being to hard/harsh on my cousin's kid?

My cousin, her 3year.boy, and her 8year.girl moved into our 3 bedroom townhouse with my family of 5 (my mom, dad, 2 brothers 17yr and 10year, and me 18yr.), because she had a huge fight with her boyfriend/husband (they are not married but have 2 kids) for the third time. So I gave her my room and I slept on the couch, but a week and half later she went back to her guy. My mom told me that she said I was being too harsh on her kids that's why she moved out.
Was I being too harsh on them because don't let them use my laptop, didn't let them yell or run at 6:30 in morning, make them clean after themselves, make them drink more water instead of pop and juice, told them to say please and thank you, didn't let them have candy or cookies in the morning and to respect their mom more.
or is she just a bad parent letting your kids do what ever they want? Her 3 year old screams and shouts she gives him her iphone or anything he wants and lets him hit/bite her and his sister and throws stuff at her too. Then her 8 year old boss her around, she leaves the house without even telling her mom nothing, she lies all the time, and her mom buys her anything she wants (she a phone, DSI, and a ipod). Then she's say that i'm to young to understand, what you guys think?

What does sent as a text message mean? (iphone issue)?

So, i've been using a iphone 5 for a month and i just realized that when i'm using sms, usually my texts send as "green balloons" but sometimes the color turns "blue"and says "sent as a text message"
i'm confused lil bit:/ what does "sent as a text message" mean? And what's the difference between blue and green texts. Will it send to different message box or shows different to who i text?

Getting paid when deployed-navy?

I'm just curious, I see people on here saying that when they were in the navy they went to 20+ countries. When they were there, they must have to pay in the national currency… So everytime they go somewhere new do they have to withdraw different cash? Do they end up with a bunch of extra money from different countries?

Of course I don't mean Afghanistan, but my friend in South Korea has bought McDonald's, Krispy Kreme, and an iPhone 5! Does he use a credit/debit card, US dollars, or whatever the Korean currency is? I can't get ahold if him now to ask him.

I found an iPhone 4, can I use it?

I found an iPhone 4 and it is still linked to a verizon number and the verizon network. It hasn't been locked but no one has claimed it. Is there any way for me to get rid of the verizon number and network and flash it to a prepaid carrier?

How to unlock sprint iPhone 4S? - 1

I have an iPhone 4S on the sprint carrier. I was wondering if it is possible to unlock it and put it on a prepaid service such as virgin mobile or simple mobile etc. Also i would prefer it to get unlocked while its NOT jailbroken because that just makes the phone slow down alot! I know there are ways to unlock the phone with out it being jailbroken however i don't know if it works with the sprint iPhone 4S with up to date iOS.

Help getting past the Apple ID credit card part?

My friend gave me his old iphone 4 after he got the 4S and i enjoyed free apps using his apple id for quite awhile, but hes off in another country now so i thought i would sign out and make my own. I signed up but every time i try to use it, it is asking me to review my account information, and there's no option to pick none. Is it just the device i'm using? (i'm using the iphone 4)

Everywhere i go seems to say that there should be a "none" option, but i don't see it. After browsing through other people's posts on various websites about a similar problem and being directed over and over to apples support page it seems that, from what i've understood so far, if you have an unreviewed/activated apple id you need a credit card, if you don't have one and are starting from scratch, then you won't need a card. I'm pretty confused. In recap, i made an apple id and every time i try to use it it wants me to review my account, but when i do there's no option to pick "none" in the credit card section. Anyway how i can fix this? If i absolutely need to i can add a card, but id rather not. If it does come to it, can i remove the card information and still have things work properly such as the app store? Free apps of course.
