Optimus, Orange’s Portuguese brand, is getting set to release iPhone 4 but the price they want for a network-locked device will make it one of the most expensive places in the world to buy one, reports “TiPb” (http://macosg.me/2/r5).

The iPhone 4 16Gb Black will cost 679,90€, and the iPhone 4 32Gb Black is 769,90€. That’s a 70€ price bump, notes “TiPb.”
