I'll have to warn you guys, regular phone wiring isn't twisted either.  I
installed one line with twisted-pair wiring.  There are more than one pair
in this cable, and I guess you could do multi-line that way.
The blue Ethernet cabling looks like it would do nicely for modem-line
wire.   Don't expect much of an improvement if you change from normal
phone wire to twisted.  The most I've gotten out of it is one higher
speed than my old wire did.  Of course, if your old wiring is very BAD,
you may see a bigger improvement.
Aside from the wire itself, there are some precautions to follow for a modem
line.  If possible, don't run a modem on a line that's shared with a lot of
phones.  Don't run your wiring parallel to an electric (Romex) cable unless
it's at least 12" away.  Cross Romex cables at a 90 degree angle.
