The Devices which are officially supported are :
Samsung Galaxy Nexus, LG Nexus 4, ASUS Nexus 7, Samsung Nexus 10.
Being an unscratched developer's edition, there is nothing new to play with OS at this moment.Also, something to note that WiFi works properly but there are some bugs in 3G/EDGE Data, hence it doesn't work.
The issues regarding specific Nexus Models are posted here: <a href="https://wiki.ubuntu.com/Touch/ReleaseNotes#Device_Specific_Issues" target="_blank" rel="nofollow noopener noreferrer">Touch/ReleaseNotes - Ubuntu Wiki</a>
Just few required Applications like Gallery,Dialer,Camera,Media Player,Browser,etc. are available.The developer can install their apps in Ubuntu ROM via SSH as Terminal application is not available.
If you're OS X or Windows or anyother than Non-Ubuntu user & you're expecting to flash ROM like you were flashing Custom ROMS of Android,then it's not possible.
You have to boot Ubuntu in desktop & then #-Link-Snipped-# & update the repository.You'll also need some additional tools for flashing Ubuntu on your Android device. (Steps are given in link below)
Eager to Flash Ubuntu in your phone ?

I believe Ubuntu for Phones will take almost 6-7 months to get mature, well that usually depends upon the Canonical community & Developer's work though.
Have to wait 'till October 2013 for official Stable Ubuntu ROM,I guess 👍
