Last supported IOS for 2821 ISR & 3560G Switch

[Philbert2k]

I'm trying to find what the last supported IOS versions are for my 2821 ISR & 3560G Switch.  

Currently running the following images:

2821: flash:c2800nm-adventerprisek9-mz.151-4.M1.bin

3560: flash:c3560-ipbasek9-mz.122-55.SE12/c3560-ipbasek9-mz.122-55.SE12.bin

Would like to upgrade to the latest available just don't want to brick by using the wrong version.  (I do know they are EOL/EOS)

Thanks!

It is hard to get info for those devices that are EOL, aka retired.
there might be a way if you logged in to Cisco support site and look at download page.
there was a link but i ahve to test it to see if still works.....
check in later

For c3560,  version 12. 2 . 55 does look familiar. i think for those older switches 12.2 with 55 is the latest or the last update provided.
