Apple is expected to release white iPhones by the end of the year, but that may be delayed. If you want to turn your current iPhone 4 white, you can do so with some select NYC iPhone repair shops. Many iPhone repair shops in NYC are able to replace a broken screen, but only few can convert your black iPhone to white.
Please note that converting your iPhone to white entails replacing the front, back, home button, and side panel. These parts are hard to find and typically not found domestically. The cost, as you can imagine, can vary per NYC computer repair shop, but you should be able to find one that does it within the hour you drop it off. Hey, do you really want to be without your iPhone for long period of time. Your calls are important!
Apple certified shops perform the iPhone 4 in white, but there are some that are not certified who can also perform the repairs. Certification ensures trust, but also make sure there is a rock solid warranty as well.
