The bottom half of the touch screen don't work
What can I do to fix this problem
iPhone是初代iPhone（中国又称iPhone 2G）。型号为 A1203，存储容量有4GB、8GB、16GB可选，机身颜色仅有黑色搭配金属铝。维修初代iPhone是容易的，需要耐心，其他工具和焊接。
Tammy Adams, you can try with a reset and a restore first. If that does not work, disassemble your phone, check the cable for proper connection. If it is properly connected, no corrosion or debris on the logic board, replace the digitizer. Check this video to see if you are up to that task. Also remember that the Original 2G iPhone Glass repair will cost you more than the 3G iPhone Glass. The 2G uses an assembly of the glass, digitizer, and LCD screen. the assembly is available at places like this. Hope this helps, good luck.
