AOSP support for Xperia devices

Recently, I had the opportunity to talk at XDA DevCon in Manchester about Sony Mobile’s approach to AOSP. We’ve seen a lot of engagement on the subject – lots of comments, lots of questions – so we wanted to share more details and clarify a few points about the work we do to provide binaries and source code to community developers. The binaries and source code are then used as a base when community developers are compiling their own custom ROMs.

This way, advanced developers could try it out and evaluate it, in a similar way to how we did it last year with the ICS alpha release. Please note that there are several limitations to this alpha software, for instance the UI look and feel is not updated to final Sony Jelly Bean software. Read more after the jump!
