is any of you here received a Receipt# that starts IOE??   

Same here.  We received IOE also.  What service center are you? My SC is Nebraska. 
  I asked few of my friends about this IOE and most of them got approved for 2months only.  

yes. 
I130, my petition was in Texas, and with IOE receipt number. 
There is no way to track the status with IOE by yourself at all, you HAVE to call to talk to USCIS rep to get the most up to date status. Even automatic USCIS phone bot will not have information about your case.
AFA I was told, our cases fall into new efile system and a lot people have petition approved with 2-3 months without expedite. It only took me 42 days to get it to approve.
 
good luck to you.
