iPhone 4 Repairability Score: 6 out of 10 (10 is easiest to repair)
The iPhone 4 is held together primarily with [lots of] screws, sans tabs, and limited adhesive.
The rear panel and battery are both easy to remove and replace (provided you have the right kit and/or correct screwdriver).
Apple is using Pentalobe screws to secure the rear panel and keep people out.
The LCD and glass are fused together, making repairing a cracked front panel more costly.
During disassembly, your finger oils interfere with the iPhone 4's RF grounding contact points, so we recommend you wear gloves while performing any repairs.
