Frozen iPhone-apple logo with black screen 3G

If you read the many posts about this, it takes more than just pressing the home button when plugged into iTunes. Did you do a reset - press both home and sleep/wake buttons until the Apple logo appears?
Recovery mode:
1. Start iTunes.
2. Plug USB end of cable into a USB port in the back of your computer, not an external hub or keyboard port. Plug phone port end directly into the phone without using a dock.
3. Press BOTH the home and sleep/wake buttons until the Apple logo reappears, then continue pressing the home button alone until iTunes sees the phone in recovery mode.
4. Follow the prompts to restore.
If the phone doesnt respond to any of this, there is either a hardware problem or you have hacked firmware installed. In either case your only solution is replacement.
