Joiku??? WTF???
Not sure about that name.
If you search for "Joiku" and "Sami" (or Saami), you'll hear what it means. It's a Sami (OK, Lapland's closest if you google) 'folk' song.
It actually sounds like the noise you'd make if your toenails were being pulled out - slowly, one-by-one, whilst the rest of you is being roasted on a sauna set to 100 degrees C.
Marketing at it's best, huh? Sami friend of mine sings it. But she does it best face-down in a pool of vomit. Hers. Now, that's Unlimited Mobile.
