What's the maximum bone count does iPhone support?

My sys is iPhone SDK 3.0, OS 2.2.1/3.0


a 3 bones animation runs well in my project now, but when I try to render a 26 bones animation, it got a error, EXEC_BAD_ACCESS.

Are there too many bones?

or other causes?

thanks a lot !

Got the result:

by GL_MAX_VERTEX_UNITS_OES, the max vertex units is 3 on iPhone 3G.  4 on 3GS, 4 on simulator.

by GL_MAX_PALETTE_MATRICES_OES, the max palette matrices is 9 on iPhone 3G, 11 on 3GS, 11 on simulator.

in my proj, too more vertex units caused that issus.
