If you hadn't heard, the value of Russia's ruble is tanking -- and that's starting to make online store operators nervous. Apple tells Bloomberg that it has frozen internet salesin the country while its workers "review pricing." The company hasn't said when the store might come back, but it's a drastic step when Apple and many other tech companies usually deal with currency changes by adjusting prices and calling it a day. Until the official store returns, Russians will have to be content with going through third-party outlets (such as carriers and retail chains) to get their iPhones and Macs.
