iAd banner initial delay - when fixed ?

Hi,

Is there any chance to fix initial delay for iAd banner in Corona SDK ?

There is information in docs that this delay exist in iOS6 and takes 30-60 seconds

This problem is still valid ? Any ETA to fix this ?

I could compare iAd plugin to tapfortap plugin, that works very fast both reaction for tap and initial time to show ad unit.
