First of all, congratulations!!! That's awesome! 
I think at this point your best option is to wait for your new card to arrive before you apply - I think they'll expect to see the copy of your new green card in your application package, since their records will show that you're approved. 
Alternatively, if you're ready to apply now, then send it in right away, so that they might think you hadn't received the approval notice before you applied!

Finally got my GC in hand....gosh VJ has been a family right from when the process started in 2013 up till date.
 
for those still waiting remain strong yours is around the corner.
 
I’m so happy now, time to start the final stage of the journey N400.
 
i appreciate everyone who contributes, the information, the guys who update timelines, spread sheets y’all wonderful!

Went to USCIS Delaware office to get I551..worst experience ever, officer smelled of smoke, I had a hard time holding my breath, then she screamed at me that why did I come to Delaware, I replied..'mam there is no appointment in my state, this was the closest I could find and my GC is expiring tomorrow', she was like thats no excuse, she refused to see my application, then I had to beg her and she agreed eventually, and in her anger she gave me only 6 months stamp, and told me to go back to Baltimore office asap to make that extension to one year. I am hoping to get my case settled in next 6 months. 
Is there any filer from June first week 2016 who is still waiting, or am I the only one ?

You are not alone. Got the same response. Mine was send on June 8, 2016
