My friend was offered $38 for his iPhone 4S because the (+) volume button and the power button were broken. After $50 in parts/tools, he received $220 for the fixed phone. In addition, I switched from Verizon to T-Mobile three months ago with my unlocked CDMA iPhone 5, originally purchased outright in 2012. Since T-Mobile is on the GSM network, I purchased an unlocked GSM iPhone 5 on eBay for $250. The buttons barely worked and the screen was very scratched, so I swapped the screens and buttons with my CDMA phone. I now have a GSM iPhone 5 in amazing condition, and sold the CDMA iPhone 5 for $220 to a third party buyer.
The repairs were both flawless. They were both time consuming (2-3 hours each), but this was also my first time.
Please make the guides clearer about the specific tools required. Sometimes the tool list jumps into two columns, and this makes it hard to look at as a "check list." I missed the fact that I needed a flathead screwdriver for my repairs and had to improvise with a flat hair clip.
