Apple on Monday released version 4 of its mobile operating system iOS, formerly called iPhone OS, to fix 65 vulnerabilities. The bugs could allow an attacker to run arbitrary code on an affected device, conduct cross-site scripting attacks or obtain sensitive information, Apple said in a security advisory. iOS 4 is available for iPhone 3G and 3GS, along with second- and third-generation iPod Touch devices. Meanwhile, iPad users will have to wait until fall for the same update. — AM
