Do i need a new battery for my Iphone?

When I plug it in it boots up and it runs for 5 seconds then a spiral thing shows up in the middle of the phone and it shuts off before I can type in my code. This happens right when I plug it in. The phone won't even work when it is plugged in and it just shoes the battery with the energy symbol under it. I had it plugged in all night and still showed the same thing so i'm thinking i need a new battery.

Added (1). I should add that it is an iphone 4

I need to transfer music from old itunes to iphone

I recently got the new iphone5, and need to download music onto it. Instead of downloading 1000+ songs I was going to just download my sister's music onto my phone. But, when I plugged in my phone to her computer, iTunes would not accept it. My sister won't download the new iTunes because she's afraid it won't let her download more music/apps onto her iPod since it's a very, very old generation. Is there anything I can do? Is this actually true?

IPhone Restore +Redsn0w jailbreak?

I have question about Jailbreaking.
Yesterday, I Restored my 3GS iPhone to iOs 6.1.3
And now i don't know what to do? And when i try to activate it it says after a few minutes "Your iPhone could not be activated because the activation server is temporarily unavailable. Try connnecting your iPhone to iTunes to activate it, or try again in a couple of minutes.
I already checked itunes and it also saids " We're sorry we're unavailable to continue with your activation at this time.

One last question when i try to Jailbreak. Why does it not show below Extras (above Jailbreak) my devices when it is currently in my laptop? For Ex. Devices: iPhone 3gs iOs 6.1.3 ( 6.15.00)?

Right,
i have an iphone 4 its been working fine since i've had it then today i was texting a friend and then i put it down for 10 mins max looked at it again it wouldnt turn on and it wasn't dead, so i walked up stairs, plugged it in by the wall it turned on and everything and it told me to connect too itunes, i unplugged my charger and it went off and it said it was 100% charged, so i plugged it into my laptop and it would switch on until the apple comes up waits like 2 mins then goes of and trys doing it again.
