Independence
iPhone Duo Guide is an independent site and is not affiliated with, endorsed by or sponsored by Apple Inc.
iPhone is a trademark of Apple Inc. We don't accept payment for coverage, and no retailer or carrier pays to be listed or ranked.
How we work
Editorial standards
Sourced
Facts link to where they come from: Apple's own pages first, then published reporting. Specifications and prices come from Apple unless we say otherwise.
Labeled
Rumors and reports are marked as such and kept apart from what Apple has confirmed.
Hands-on, when stated
When a page reflects our own use of the phone, it says so and explains what was done. We don't publish measurements we haven't made.
Reader contributions
Reports, poll results and app compatibility notes from readers are reviewed before they're published and are labeled as reader-reported.
Dated
Every guide shows when it was last updated.
Corrected in the open
We fix errors promptly and note significant corrections at the bottom of the page.
Corrections
If something on the site is wrong or out of date, tell us or email corrections@iphoneduoguide.com. We fix errors promptly and note significant corrections at the bottom of the page.
Affiliate links
Some links to retailers are affiliate links, which means we may earn a commission if you buy through them, at no extra cost to you. Affiliate relationships never decide what we recommend.
Advertising
We aren't running ads yet. Our advertising page explains what we'll offer and the rules sponsors follow.
