I’m the one who love Sony Erricsson Camera application and if you love the Xperia X10′s too, i am sure you will be happy to know that Sony Ericsson wont be getting rid of the camera application. Sony Ericsson Xperia X10 can expect the Gingerbread update to arrive at the beginning of August, according to official.

So we have to wait till August, for Xperia X10 2.3 Android update.
I also have an iPhone and in my opinion, I think the X10 is better. Is a hassle to have to use the iphone and be tethered to iTunes all the time. There are already thousands of apps available out there for the Android OS. The touch screen interface is probably better on the iPhone. But the user interface and features on the X10 is, in my opinion better.
