Hi, I think this is a great idea! I'm getting an error though:

gammusms2android.rb:73: undefined method text' for nil:NilClass (NoMethodError) from /usr/lib/ruby/vendor_ruby/nokogiri/xml/node_set.rb:239:ineach'
from /usr/lib/ruby/vendor_ruby/nokogiri/xml/node_set.rb:238:in upto' from /usr/lib/ruby/vendor_ruby/nokogiri/xml/node_set.rb:238:ineach'
from ./gammusms2android.rb:68

Any hints?

Hi,

I had the same problem as @HolsteinerLisel, looking at the exported data, the 'sent' messages don't have a 'dateenc' field, so this won't work.
