You could use the LGPL version during development and only switch to the commercial license once you go live.

Has the commercial agreement been changed? The terms of the commercial license specifically prohibited that.

It does? But I thought it is possible to use the LGPL version to develop apps. It is just not possible to distribute them through the app stores because of the app stores, not because of Qt. You don't use the app store to deploy the development version of your app onto you development device.

That's all true. However, the commercial license included this:
"You must purchase a Qt Commercial Developer License from us or from one of our authorized resellers before you start developing commercial software. The Qt Commercial Developer License does not allow the incorporation of code developed with the Qt GNU LGPL v. 2.1 or GNU GPL v. 3.0 license versions into a commercial product."
Basically, you have to choose LGPL or commercial before you start your project. You can only transition from commercial to LGPL, not LGPL to commercial.
They do that to prevent specifically the thing you're suggesting, though they're probably aiming it more at large companies with many developers, so those guys don't just buy 1 license.
