I'm in a quandary. I know the new iP4GS will debut in September. But that's still three months away and I'm suffering with a two-year-old 3GS. A quickie white iPhone 4 unlocked will set me back 600 euros plus tax, about $900. Think I should get it and sell it on eBay in September? Of course, I can't use it until I get back to the U.S. because I need to order a SIM cutter from eBay. No one here, apparently, sells "pay-as-you-go" microsim cards. The lady in the Movistar store tells me all microsim cards are for subscription plans only. What should I do?
