Answers:
If your friend cracked your password next most promising you give it to him... seriously, he probably tricked you into giving it to him in some road.
There are absolutely programs that can crack an msn password... such as passware... but the likelihood of him using other scheme to attain it is more feasible.
Hacking BACK is off the record. I suggest you report the incident to the authorities and allow them to business near "your friend".
biddable luck.
