iPhone 3G Stuck in Recovery mode (need a fast help!)

WHile I was updating my iPhone, the progression bar got stuck at around 10%, so I stupidly unplugged the iPhone, witch went into recovery mode. So now, when I press the Recover and Update thing, it again gets stuck at around 10%. So I'm kinda left without a phone, witch I seriously need :/

Usefull info: The iPhone was unlocked around 2 weeks ago, and this was my first connection to iTunes, witch automaticly updated my phone. The version before the update was 4.00 I and it was updating to 4.00.1 ( I think). The iPhone was empty, default music, 4 pictures(taken with the camera) and a GPS. The iPhone was bought around (3 weeks - 1 month) ago.

Sorry about my English, and I would serously be happy if I could fix this in 3-5 days D:

Thank you
