Hi, that's right, of course the new iPod touch does have a gyro as mentioned in the post. Actually, the website only uses Flash as required — it automatically adapts to use 3D capabilities in Safari on mobile and desktop. We'll use built-in facilities as other browsers begin to enable this, but Safari is solo at this point. Other browsers don't have any built-in ability to display images in 3D, so we adapt to use Flash in those cases because Flash does provide the necessary 3D transforms.

The resolution of a panorama is up to 4096×1011 pixels depending on the field of view captured. We think it's absolutely excellent for sharing. We're constantly working on even more sophisticated computer vision algorithms to increase fidelity and allow for more varied motion paths.

Low framerates are not the norm on mobile. In fact, we render at about 60fps. There can sometimes be initial jumps right when you first load a panorama as the browser's still doing a bunch of prep work, but it clears up after 1-2 seconds. If you're seeing consistent slowness, please get in touch with us so we can decipher what's going on and, if appropriate, address it. Note that the gyroscope data arriving in Mobile safari isn't as fast as one might hope — Apple only sends the data to Safari at a rate of 20fps (touch motion will proceed at 60fps despite the gyroscope's slower update rate.)

We're very, very serious about performance, so whenever we have reports to the contrary, we want to address them immediately.

Josh, sorry we didn't reply earlier, but thanks for the great suggestions. By the way, in 3.1 you can save panoramas and re-open them in-app. This lets you do what you were hoping to save battery and not have to upload right away. It still requires a few steps, though, so we'll try to make it more streamlined in the future.

Yes, you can still use the Save and Email options without internet. In the case of Email, your panoramas will go in the outbox just like a typical email, and will send when you're re-connected later. In the case of Save, you can re-open your panoramas into the app later and, if you want, Upload them.

On the main capture screen, press the action button in the lower-left corner. Then select your panorama, and it will re-open it automatically. Although it's saved as a flat photo, 360 Panorama knows how to "wrap" the image around you just like when you originally captured it. Best of all, when you upload it, you don't lose any quality.

Important tip: If you try to open a panorama but it just returns you to the capture screen, this means location services are disabled. To fix this, go to Settings -> General -> Location Services, and enable Location Services for 360 Panorama.
