How totrack an ip address

"how can u track that ip address"

----->>>first of all, it might be a dynamic IP address tht keeps changing every time you connect.. only the ISP keeps track of who was logged onto IP at what time..
and
if its a static IP then that person might've used a proxy to send that mail..(hope you know what a proxy does)...

on top of that
he might've used an internet cafe to post you the mail..

AND
ip tracing can atmost give an indication to which city the ip belongs to, not the exact location..

so its not at all simple tracing the ip..

HOWEVER.. here are
Some Visual Tracing Tools

"is there any chance to hack through phishing"

yes, there's a lotta chance tricking the victim into entering his login and password in a fake log in page created by you.. this is called phishing.. it is dome as follows:
1. lets say you wanna hack his orkut passwrd.
2. make a webpage which looks like "orkut" but actually is a fake.
3. now the victim would enter his id and pass into it..
4. the fake log in page would save it and later give it to you..

to do this use a software called "Fishing Bait 2.5"

this software would create a fake log in page of any site you want.. and you won't have to code yourself in HTML.. "how to hack some ones password through password dictionary"
