If you are waiting to apply so that your new grades will come through and your gpa will look better when the "August" schools see them, I do not think that is a good plan. First of all, you are more that welcome to tell schools that you will have updated grades shortly and that they will be good, and also, any advantage that you might realize by waiting to apply with a stronger GPA will be lost due to your delay in application submission. I just mean that if you consider the disadvantage of waiting to turn in you app versus that of slightly lower grades, the trade off isnt worth it.
Apply to them all as soon as you can.
