Yes, the old
Code:
while read rec; do 
    # process stuff
done < file

construct is notoriously slow and thus should only be used
on small to moderately big files.
I would go for Perl.
Without having looked too carefully at your processing,
and without even having tried for correct syntax
some Perl statement like this might do?
Code:
$ perl -ane 'push @ary,$F[1] if /3G/;END{$"="\n";print"@ary"}' file_to_read_from
