Hi Guy,
I carried out a video for the owners of iPhone who wish to see appearing the icon FieldTest
(Warning only for the Jailbreak mobile)

1/install ifunbox
2/Go : Device/Applications/FieldTest.app and copy info.plist in your desk
3/Open info.plist (this in your desk) and delete line "SBAppTags" (you can see "item 0 = hidden")
4/ copy the new file : info.plist (just crush the old file).
5/ Restart your iphone and you'll see the icon
