i am running firmware 3.2U after a downgrade. i want all of my IOSs up to date to ensure that i have the best compatibility that i can get with this firmware version. here is a list of the newer IOSs that i currently have installed... IOS249 IOS55 IOS51 IOS38 IOS rev7 (what is this? 36?) that basically sums it up. is there anything missing that i should install? what about IOS53? is that necessary? i don't know whether this post is out of line or not but i thought that it might help some people as well as myself.
