Instagram for Symbian is a third party solution, it's true, but is coming on apace, with a bevy of updates listed below, filling out functionality and improving its interface, including photo and video downloading and full display of comments.

Here's the changelog for v1.9, over and above the initial version featured here:

• Added Turkish and Russian languages
• Download image or videos
• View profile image
• UI, font changes
• Connect through to Twitter (Facebook coming soon)
• Bigger grid view
• New Settings page (access from Profile page)
• View comment counts by pressing the comment button
• Refresh option in all pages
• Bug fixes

A few screens of v1.9 in action:

From the '...' menu there's now the option to download a photo to your phone's storage; (right) tapping on the Comments button gives a full view of what everyone's saying....

Sharing through to Twitter is now possible, if you want to go cross-platform, as it were(!); (right) there's now a Settings dialog, embedded from the Profile menu....

You can find Instagram in AppList, either in the Symbian client or here.

Hopefully the AppList Store is working out for you all. See here just in case you haven't already got this installed or if this is new to you. Also, if you have custom firmware installed, make sure you tick the option in settings to show 'unsigned' applications, you'll see extra applications!
