    For developers who already have finished apps in the App store, when are you switching to building updates with the newer 2.1 SDK? And when will you start building app updates (or new apps) for iPhone OS 2.1 instead of building backward compatible app updates for OS 2.0?

    Has anyone heard any estimates with at least 50%+ of App store customers will be running 2.1?

    There's at least one 2.1 feature which I would like to add to one of my apps, but not if it makes an update unusable by the majority of its current users.

    bump

    Has anyone here already submitted an app built with the 2.1 SDK and had it accepted?

    Thanks.

    I had a 2.1 app released last week; I think building on 2.1 was a mistake, since my downloads have been far fewer than expected (based on previous apps.) I've already submitted a 2.0 update.

    It may seem unthinkable that few people have upgraded, but we're early adopter outliers. I met many people at the genius bar that have never synced with a computer - ever.

    Does netcraft show iphone os version in their stats? That or google analytics for a popular site would be a good place to start.

    you can use the new 2.1 xcode to build 2.0 apps right? I know there is a 2.1 and 2.0 build setting, or should i build my apps on the older xcode just to make sure?

    I can still build 2.0 apps after upgrading my 2.0 SDK to 2.1

    I upgraded my PHONE to 2.1, and could no longer use it for debugging 2.0 apps (I got errors about incompatible debuggers, I think.) That's why I upgraded my SDK.

    I built my latest upgrade for 2.1 and submitted it to the store. Anybody know if it prevents people from downloading an app built for 2.1 if they are running 2.0?

    Yes if you app is built for 2.1 and someone with a 2.0 iphone tires to download it they will be told that they need to upgrade to 2.1 before they can download the app.

    Has anyone found any issues with building a 2.0 app for the App store with the 2.1 SDK?

    I found at least one new warning message appears (something about Bounce Zoom...)

    I had a problem with one of my buttons built in IB when I switched to the latest SDK. It kept causing the app to crash. I recreated it and it was fine. I built my app for 2.1 since I don't have a 2.0 device anymore to test it. Quite the conundrum as it seems building for 2.1 was a mistake since anybody who hasn't upgraded won't be able to download it.

    Unless you need phone/accelerometer/GPS functionality, you can probably still test a 2.0 build for compatibility using the Simulator. Then stress test it on a 2.1 device.

    Anyone know how to get rid of a "Bounce Zoom" warning message? Is there some new checkbox in the Interface builder or something?

    Hmm I submitted my latest update (which got approved) as a 2.1 build and it got approved. Didn't occur to me to build as 2.0 whoops! I imagine most people have updated by now though.. at least, I'd hope so!

    I just realized the unlocked folks are stuck at 2.0, so I guess I'll just release another update to back it down to 2.0.
