Since it's a commonly accepted fact that the new second-generation 3G iPhone will be revealed at WWDC on Monday, ZAGG sent out emails today announcing that 3G iPhone invisibleSHIELDs are now available for 20% off original prices. Expected to ship at the end of June, front, back, and full body shields can be preordered for $11.96, $15.16, and $19.96, respectively.
