please help me how to fix my iphone.. i got problem with my iphone 3gs, there is nothing appear in the screen, i even try to hold the home with sleep(on/off) button but it still blackoff. i even try to connect it to my computer but it still blackoff- no logo appear at all. so anybody can help me??? Thanks

ifa, try a hard reset. Press and hold both the Sleep/Wake button and the Home button for at least ten seconds. The apple logo should appear and your iPhone should be reset. Also, like Jeremy Scalpello suggests I would try and charge it on an AC charger for a few hours. If none of this works , I think it is time to open up your iPhone and take a look at any visible damage, like corrosion, torn cables etc. and REPLACE your battery. Good Luck.

yes, i tried oldturkeys suggestion and the apple logo appeared. now what?
