Hello iFixit, Thank you for this great service. I have two questions:

  1. Is there a good way to ad tethering to my iPhone 3GS? I heard you have to jailbreak it first and then there is a software app that will enable tethering.
  2. the battery in my iPhone 3GS no longer holds a long charge. Is there a way to replace the battery myself? Are there instructions to do this? Where can I obtain the parts, battery? THANK YOU! Best Regards, Carson

Download spirit and in Cydia, install Tether, follow the directions within. And here is where you can find how to replace the iPhone 3GS’s battery.
