So to avoid network problems and fix some calls problems it is VERY important to do this modification on the FuriouSim:

1. Here is what you will need to perform modification : FuriouSim V1.0 + One Cutter ( can be needle, Knife, small screw driver) + Multimetter (it isjust to make sure modif is well made, test on mobile phone can also be ok)

2. Make a hole on the FuriouSim try make same disposition as the 3 hole you already have on the Upper copper pad

3. Repat action for the 3 hole

4. Test with multimetter (not mandory) you must have continuity between up pad and down pad
Also after that your sim will work pretty sure on 95% of phones this including iPhone 3G.
If your ordered the sim after 24th JULY 2008. You do NOT need to make this modification.
