My Iphone 3 Screen won't come on?

I've just had a second hand Iphone 3 off my Dad as he now has an Iphone 4. I've tried turning it on and although it lights a little nothing appears on the screen, though it has been making noises and a voice has said something about voice commands. I've tried holding down the button on the top right but no change and it's also been charged for a few hours now. I've not yet put a SIM into it. The phone worked fine previously. Can someone please help me to get it working!

Is it worth using an iPhone as an iPod, or should I buy an iPod separately?

As a Best Buy associate, we're limited to pre-ordering the new iPhone 5 to September 16th and after, as to give priority to customers first. I do plan on ordering tomorrow, though, and am unsure of what GB I should get. I'm wondering if it is worth upgrading the GB on the iPhone to use it as an iPod, or if I should just buy an iPod separately. I have no problem doing either, but I'm wondering what would be my best bet. I know that iPhones aren't famous for their battery life, while many regular iPods are. I would want roughly 3, 000-5, 000 songs on my iPod or iPhone. Thoughts, anyone?

Online vs instore black friday prices?

I would want to know if in black friday the deals are the same online as in stores because the lines and people in stores is bigger than the president's thanksgining dinner.

I need some help in this because i'm not relly experienced with black fridays.

Item delivered by USPS can't be tracked?

I had ordered an iphone 4 days ago on ebay.
Currently this is what the USPS status site reads:

YOUR LABEL NUMBER LK079015769US
SERVICESTATUS OF YOUR ITEM Electronic Shipping Info Received
DATE & TIMELOCATION September 11, 2012
FEATURES International Letter
and yes the seller dropped it off to the post office
the website STILL has not updated, nor have I received the package. It is priority mail, shouldn't it have updated by now?

Added (1). Oh, the track information has just been updated on the USPS site: You entered: LK079015769US
Delivery status information is not available for your item via this web site. A return receipt after mailing may be available through your local Post Office.
Does it mean the item is in my country now? And the item can't be tracked in the express of my country
