While Vine, Flipboard, and Path have all promised Windows Phone 8 support, one particular app is still missing: Instagram. Nokia has tried to pressure Facebook into building an Instagram Windows Phone app, but so far users have had to resort to third-party applications. Instance, a popular unofficial Windows Phone Instagram app that supports viewing and uploading of Instagram photos, appears to now be blocked from using the photo sharing service. The application reverse engineers Instagram’s own API to bypass and upload pictures to the service unofficially. Daniel Gary, the developer behind Instance claims that Instagram is deleting images after they’re uploaded to the service using the third-party Instance Windows Phone app. During our own tests we’ve been able to confirm that photos do indeed upload to Instagram from the Instance application, and are visible on Instagram’s website if you’re logged in using your own profile.
