iPhone not charging, Springboard Crashing

[Darkstar752]

So last night I went to my 6-9 class with not much battery left on my iPhone 3G, and I ran it down by playing games in class to about 5%. Now the phone won't charge, I noticed last night, I've rebooted it a couple times this morning, and it crashed 2 times saying springboard has crashed and I need to restart my phone.

I've had it plugged in for like 12 hours now and it has not budged from 3%. sometimes even dropping to 2% battery. The only things I've tried so far are a reboot and restart. I just noticed that Cydia has some updates for SBsettings and MobileSubstrate, I am trying to download these now but if they don't work I'm ******. Suggestions?

Update- Phone is now went to 0% battery, it's plugged in but I still don't think it's charging. It's on the dead charging screen where it's just a lightning bolt under a red battery charging screen, I really, really need my phone to work.


Update
Here's what's going on right now, it's stuck on this screen. Not charging. I can't Restore the phone because it's technically not on and iTunes won't recognize it, it's trying to charge enough to turn on. WTF do I do, it's JB so I can't take it to Apple.
