I wrote this FAQ to show how to modify your cable. I have included pictures but I couldn't get em to work, sorry.
I will add or change a few things in the next version of the faq.

FAQ: How to modify a RJ-45 Category 5 Straight-through cable into a RJ-45 Category 5 Cross-over cable.
Version 1.0
Author: BadboyKAS

Needed tools:    A wire stripper/means of stripping the wires.
      Electrical Tape
      An Exacto knife or a Normal knife

Step 1: Identify and make sure you have an RJ-45 Category 5 Straight-through cable for best results. Also I make sure to use the RJ-45 Category 5 Straight-through for the fact that maximum network potential can be recieved. On the cable it usually says RJ-45 and or Cat 5 on the RJ-45 Category 5 Straight-through cable.

Note: Inside a Category 5 cable are eight thin, color-coded wires inside
that run from one end of the cable to the other. All eight wires are used. In a straight-through cable, wires 1, 2, 3, and 6 at one end of the cable are also wires 1, 2, 3, and 6 at the other end. In a crossover cable, the order of the wires change from one end to the
other: wire 1 becomes 3, and 2 becomes 6.

Step 2: To determine which wire is wire number 1, hold the cable
so that the end of the plastic RJ-45 tip (the part that goes
into a wall jack first) is facing away from you. Face the
clip down so that the copper side faces up (the clip
will now be parallel to the floor). When looking down on
the copper side, wire 1 will be on the far left.

Example:


Step 3:  Once you have determined if your network cable is the right one to use,  you can start modifying it. Start by making an incision with the Exacto knife about 4 inches away from the connector, you want to remove the outside layer of the RJ-45 Category 5 Straight-through cable about 1 inch. You have to cut the outside layer in a way that you can have access to the 8 color coded wires inside.

Step 4:  Cut wires that connect to pins 1, 2, 3 and 6, in other words the white wire with an orange stripe, solid orange wire, white wire with a green stripe and solid green wire about ½ inch down so that middle is cut. The wires are colored white wire with an orange stripe (connects to pin 1), solid orange wire (connects to pin 2), white wire with a green stripe (connects to pin 3) and solid green wire (connects to pin 6). Make sure not to cut the other wires. From this point if you wish to label the wires for your own use it would be a  wise decision.

Note:  Your network cable may not follow the same color pattern, if it does not make sure to identify the wires by which wire connects to each pin. Another way of finding the color pattern is to get off the little encasement over the RJ-45 Category 5 Straight-through cable tip and look directly on the connector and follow the pins to a wire. You should normally be able to do this, some RJ-45 Category 5 Straight-through cables do not carry the encasement so just go ahead and check out the connector.

Step 5:  Once you have cut the wires, using a wire stripper strip the wire ends you cut to about ¼ of an inch down. Make sure the wire is stripped big enough for you to twist 2 wire ends together.

Step 6:  The wires have to be connected in a specific sequence to function as a Cross-Over cable. The wire connection has to follow this sequence: connect wire 1 to wire 3, wire 2 to wire 6, wire 3 to wire 1 and wire 6 to wire 2. The left side of the cable is the first wire and the right side is the second wire. To form a valid connection just take the two wires and twist the ends together.




Step 7:  All the newly connected wires must be individually and wrapped in electrical tape to insulate the wires. Wrap the newly connected wires with about 2–3 layers of electrical tape making sure no stripped wire is exposed and that they are effectively sealed. Then wrap the exposed area of the newly modified network cable with about 2-3 layers of electrical tape making sure to cover all the wires including the ones you didn’t cut. By doing this you are re-bridging the insulation of the RJ-45 cable.

Step 8: Plug in and enjoy.

Definitions
RJ-45 - A connector similar to a telephone connector that holds up to eight
wires, used for connecting Ethernet devices. Also known as a network cable.

CAT 5 - ANSI/EIA (American National Standards Institute/Electronic
Industries Association) Standard 568 is one of several standards that specify
“categories” (the singular is commonly referred to as “CAT”) of twisted pair
cabling systems (wires, junctions, and connectors) in terms of the data rates
that they can sustain. CAT 5 cable has a maximum throughput of 100 Mbps and
is usually utilized for 100BaseTX networks.
