There is no doubt that the lack of multi-touch pinch zoom capability in Sony Ericsson Xperia X10 is quite annoying. But since new software update is available the things have radically changed.
All X10 users now are able to update their handsets and enjoy pinch-to-zoom gestures in the web browser and Google Maps app.
Unfortunately, this update won't be available for users with AT&T version of this device. The matter is that there are still issues with AT&T-specific Android 2.1 update and you have to update it before getting the last update version.
It's obvious that such issue will let AT&T users to think about shifting to another company with a good track record of device updating.
