Lightbulb Nernst equation and pH

How do I calculate the dependence of potential on pH in half-reaction Cu2+ / CuI? As I suspect at pH>7 Cu(OH)2 will dominate and as for pH<7?

6CuI + IO3- + 6H+ = 6Cu2+ + 7I- + 3H2O
IO3- / I- 1.08 V
Cu2+ / CuI 0,86 V
And also, can I calculate the overall potential E0 = E0 ox E0 red?
