just want to announce that I have succeeded in "supersimming" my iphone! Worked like a charm .... thanks to all the great tutorials in this forum!
Only 2 things were tricky: cutting out the sim card :D and getting a V1 card from my provider (they have already sent me one last week but this was not working).
as seen in a different thread: now we are 2 guys in Austria with an iphone :D
all the best
