IPhone with dead battery? And stuck at error 1015 in iTunes?

I got a iPhone 3g and it does not turn on by the power button. When I plugged it up it turns on and sticks at a recovery mood from what itunes said, so I hit restore and after it got over half way done it said error 1015. I have tiny umbrella installed and it says to fix 10XX recovery loop enter DFU mood so i tried that. When I unplugged this iphone it sticks at the recovery screen for another 15 seconds then shuts off and i can't turn it on in anyway unless i plug it back up. What is wrong with this thing? I paid 50 bucks for it and I'm getting really pissed. Please someone help me and not just say oh your out of your money. In tiny umbrella I did hit exit recovery and the phone rebooted and stuck at the apple logo for another 15 seconds then rebooted and stuck at the recovery screen right again. I think someone tried jailbreaking it or something and messed it up. Anyways someone please help me. Btw I have let this phone on the charger for over 12 hours so if the battery is still good it should have a charge? Maybe the battery is shot and just holds for a few seconds from when I unpluged it? I have looked into getting a new battery and how to put it in (which looks easy) But is it worth it?

ITunes WON'T erase my music

I managed to take all my music from my old computer over to iTunes on my new computer, and now I would really like to start again with a new iTunes Library, and I didn't transfer all those rubbish songs I had been sent, etc from my last library, or had been deleted…

So, now my problem is that I WANT to Sync and Erase, but it won't…

It says I don't have the extra 5GB required for this library, which is Bull cause it says my library is only 12gb, and I have a 32gb iPhone, and it says I have plenty of room!

Can anyone help? I'm presuming it's because it's just trying to add to the current library on my iPhone?

Any advice?

Thanks guys.

Added (1). No, I know how to 'un-check' music. It's not syncing is what I'm trying to say.

I want the music, library (whatever) is on my iPhone to ERASE, in exchange for what's on my iTunes on my new laptop, but it won't come off! I've tried doing everything manually but it says there's not enough space, when there's plenty!

Cheapest carrier for iPhone4?

Since the iPhone4S is coming out, the iPhone4S is at a really good price right now and I was wondering what carrier would be best? All I want is unlimited texting and caller ID but I know with any iPhone, you need a data plan if it's not prepaid.

Some carriers have the iPhone4 at $0 with $55 on a monthly plan, some have it for $50 with $50 monthly but what would be the best carrier quality wise and for price?

Added (1). Typo- the iPhone4 is at a really good price right now* not iPhone4S

Can you buy an unlocked iphone 4s without a sim card?

I wanna get an iphone 4s for virgin mobile, but the prices online are way too expensive. So i thought about getting an unlocked iphone, but my phone now (rumor touch) doesn't have a sim card. So can i still buy the unlocked iphone and just buy a new sim card on virgin mobile for it or do i have to buy the really expensive iphone from their website?

Imovie iphone app fails to upload to youtube?

I've been trying to upload a video for 2 days now that i made on the imovie app by clicking share to youtube. The uploading to youtube bar starts and gets to the L in uploading snd then says failed to upload to youtube.
