Create a Micro-SIM to SIM Adapter
To enable use of an iPhone 4 Micro-SIM within an iPhone 2G or iPhone 3GS, this procedure details how to create an adapter from the existing SIM card; be aware that this conversion renders the original SIM card unusable.
Because a replacement SIM card is included with new iPhone 4 purchases and the previous SIM is rendered inactive during the activation process, the original SIM card becomes unusable.
Step 1 | Create a Micro-SIM to SIM Adapter
Assemble the necessary tools and components, including [list all tools and parts mentioned elsewhere in the guide].
Employ an XACTO knife with a suitable work surface, ideally a self-healing cutting mat.
Use a number two pencil.
A straightened paperclip or the provided SIM-card removal tool can be used.

Step 2
Using the SIM eject tool, extract the SIM card from every iPhone.
The iPhone 4's SIM card tray is located on the right-hand side of the device.
Locate the SIM card tray, which is situated on the upper edge of all older iPhone models.

Step 3
Carefully use a pencil to outline the dimensions of the Micro-SIM card onto the surface of the existing SIM card.
Carefully align the wires with their corresponding counterparts situated underneath.

Step 4
Employ an XACTO Knife and carefully incise along the traced guideline.
To prevent the knife from slipping while cutting, initially apply gentle pressure to create a shallow guiding groove in the plastic. After establishing this groove, increase the force to complete the cut. Alternatively, drilling five small pilot holes with a fine drill bit at each corner will also serve to guide the knife.
For a precise score line on the SIM card, apply heat to the Exacto knife tip using a small torch or cigarette lighter; repeated short bursts of heat may be necessary because the blade cools rapidly.
To finalize the SIM card slot creation, turn the card over; the previously cut notch’s shape should be visible on its reverse side, allowing for a more precise completion of the slot by cutting from this underside.
Carefully extract the SIM card portion that was previously removed.

Step 5
Carefully slide the Micro-SIM Card into the prepared opening within the SIM card holder.
To accommodate a Micro-SIM that is not initially compatible, carefully remove additional plastic material from the opening using the knife.
To compensate for an oversized opening, secure the Micro-SIM card within the slot by applying a piece of tape to its rear surface—the side lacking gold contacts—and then carefully remove any protruding tape with the knife.
To ensure the Micro-SIM remains securely in place and avoids obstruction during removal, consider applying tape regardless of whether the hole's dimensions are precisely correct.

Step 6
Verify proper functionality.Using an adapter, a Micro-SIM card was inserted into an iPhone 2G for testing purposes, confirming full functionality.
