I tried account-plugin-butterfly today from extras-testing and found it working.
for some reasson, I got some contacts with no name (possibly they did not have names in my messenger).

Apart from that, I got most of my other contacts (I had only about 50 contacts in all).

I tried searching "haze" but could not find it (is it same as hermez?).

Anyway, I got my MSN stufff working woth "account-plugin-butterfly"
(not sure if it drains battery faster as yet to use it more)..
