Hi, I have following problem. Few days ago, i changed battery in my iPhone 3G. But i have problem with new battery and now even with the old battery. The iPhone is almost dead. Everytime i try to turn on, it shows only charging screen. Even if I connect it to my laptop or to electricity. I don't know where is the problem, I tried restore but it didn't helped too. I even bought a new one battery, but without result. Please help me, I'm really desperate. Where is the problem? Thanks a lot. PS: Excuse me for my bad english, I come from Czech Republic.
