It's that time of year again. Do you upgrade to a new iPhone or hold out for next year's models? Or, do you just let us make that decision for you? Thanks to our friends at Mobilefun.co.uk, we've got a silver iPhone 7 (32GB) to give away this week, complete with one of the accessory specialist's cases "for life." Even if you don't win, you can take advantage of this promotion and get a free, clear shell for your 7 or 7 Plus by signing up to the retailer's newsletter. Once you've received your cover, you can always unsubscribe if you're not interested in the tips and offers, and you'll still be able to claim another free iPhone case every time you upgrade (hence the "for life" clarifier). As always, you can enter the competition up to three times via the widget below -- after you've read the rules, that is.
