Unless your phone has a graphics chip that GSMArena doesn't list or a new update removed that requirement I'll find that hard to believe. Instagram's app page says it REQUIRES an OpenGL GPU when I downloaded it.

Yup, the notice is still there. So basically your phone has an "unlisted" graphics chip if it is indeed working and you are using the official Instagram app. I have an old Galaxy Fit at home with Android 2.2 and Instagram is listed as incompatible last I checked.
