SDL 1.3 & iOS 4(iPhone)

I’ve been toying with SDL 1.3 on iPhone for a while. Recently, since iPhone OS & SDK got updated(multitasking and stuff), I’ve encountered with some problems.

Now, if I press “home” button my application no longer exits, it just minimizes (I’m getting SDL_WINDOWEVENT_MINIMIZED), but when I reactivate application(I am getting SDL_WINDOWEVENT_RESTORED), I just get a black screen and SDL error : Couldn’t find display mode match
I mainly use 4429 revision’s snapshot. Today I tested this behavior with more recent revision (4472) and I got same black screen, but no error this time.

I just wanted to ask, maybe I am doing something wrong, maybe there is a way to restore Window and OpenGL context?
