Qt technology preview releases are not intended for use in commercially deployed applications. Rather they are released to publicise and encourage feedback on both capabilities and API features and structures.
The Qt developers are looking for feedback on the 1.2 release, in advance of shipping with MeeGo 1.2 in "early 2011". Qt Mobility 1.2 will also be included in future versions of Symbian and will likely be made available for existing and older versions via the Smart Installer.
The current technology preview does not include a Symbian .sis file due to the (im)maturity of the backend for the Connectivity module on Symbian. However, this is expected to be rectified at the beta stage.
In addition to the MeeGo backend work, the Qt Labs blog highlights two significant additions in Qt Mobility 1.2: Connectivity Bluetooth and Connectivity NFC (Near Field Communication).
NFC is set to be a hot trend in 2011. The majority of Nokia's future Symbian^3 and MeeGo devices are set to include NFC. The first device with NFC support is the Nokia C7-00. However, currently, the NFC chip is the C7-00 is inactive; it is expected to be 'activated' by a future software update. As a result, NFC testing will need to be done in the Qt Simulator, until such time as the necessary back ends are completed and NFC supporting hardware is available.
