The days of ignoring WinZip's incessant nagging that you actually pay its registration fee may be long gone, but that isn't to say the file compressing firm hasn't learned from your failure to pony up. WinZip, the Windows user's go-to compression software since the early nineties, is now available on iOS -- free of charge. The mobile utility will let users open Zip attachments from email, browse compressed files and extract encrypted archives. Actual compression of an iOS device's files, however, will still need to be done on a desktop computer.
