Chazepping, it's interesting to me that while I have no first hand experience with PAPIMI, I started reading a bit about the theory on a couple different web forums close to 2 years ago. Since then, there have been one or two people who made a general "what can I do for help?" general help inquiry on a web forum. I replied along the lines of "you may want to look into PAPIMI", and there have now been 2 different people who've replied back saying "thanks, I tried it, and have experienced great results".
Following this line, after seeing your inquiry I revisited some of my saved URL sources for PAPIMI. I get the impression that things have changed or slowed down with the advancement of this technology. What this means? I do not know. Are you within reasonable proximity to Greece? Check the following link and the question may make more sense to you. Again, I do not even know if this group is still active, their last web page update was over 12 months ago. Good luck!
