title: How many 1024*1024 pngs can be load in openGL for iphone without having the app crash in the device ??
body: <p>Approximately what's the maximum number of 1024x1024 32 bit .pngs  which can be loaded at the same time with openGL in iphone ?, without risk of the app crashing.</p>
  
  <p>And  .pvr ? a much higher number ?</p>
  
  <p>If I need a huge amount of textures in my game, is healthy to keep loading and calling dealloc to not overload the memory with all the textures ?</p>
