We've given away a few iPhone 5s in the past, but this is the first opportunity we've had to hand out a GSM-unlocked version. Also known as the A1428 model, this particular iPhone will get you HSPA+ on any GSM network around the globe as well as dual-band LTE (for use on AT&T in the US and Rogers, Telus and Bell in Canada), and it's thanks to our friends at CloudOn for offering the chance. CloudOn is a free iOS and Android tablet app that lets you create, view and edit Microsoft Office files and link them to Dropbox, Box and Google Drive, so head on over to the App Store or Play Store to check it out. Before you do, however, leave a comment below to enter! If you're looking for ideas on what to say, CloudOn wants to know what would help you become more productive on your iPhone -- perhaps you can toss them a few of your ideas. Good luck!
Update: CloudOn just announced version 3.0 of its service, which will offer iPhone compatibility and optimization with Android smartphones and 7-inch tablets.
