We're in the midst of landing some new low-level telephony stack 
improvements that will enable us to land MMS support in the Message App 
( ETA is TBD, but definitely post 14.04 ).
The major change that needs testing is the fact that we're changing how 
our stack provisions the GPRS data required for the phone to provide 
Internet connectivity.
We currently use a desktop package called mobile-broadband-provider-info 
( aka mbpi ) to do this in our current builds.  As
mbpi was never meant to support the provisiong data for MMS, so we've 
made a decison to move to a new database ( apns-conf.xml ) which is 
currenty shipped as part of our system images.  This change will also 
enable us to better support MVNO SIMs in the future as well.
We also continue to query mbpi and will additioanlly add any 
non-duplicate APNs found the specific operator queried.
To test this change, you'll need to manually delete the gprs settings 
file created by ofono, as provisioning only occurs once, after which the 
required settings are read from this file.
Also, your mobile data connection *may* take slightly longer to connect 
the first time after rebooting the phone.  You also may notice that the 
3G icon flashes on and off while this process is happening.  Once NM has 
connected mobile data for the first time, you should no longer see this 
connection delay after rebooting the phone.
We've tried to cover all bases and ensure that this switch does not 
cause people to lose mobile data connectivity, however if this does 
happen, please file a bug against the android project and we'll ensure 
that the provisioning database is updated.

Additionally, work is in progress on a settings UI for manual APN 
configuration, however I currently don't have an ETA for when this will 
land.  Progress can be tracked here:

To Test, please follow these instructions ( verbatim ):

$ ubuntu-device-flash --channel devel-proposed
$ adb shell

# mount -o remount,rw /
# add-apt-repository -y ppa:ci-train-ppa-service/landing-019
# apt-get update && apt-get install -y ofono network-manager
# cd /tmp
# wget 
https://launchpad.net/~ci-train-ppa-service/+archive/landing-019/+files/lxc-android-config_0.161_all.deb
# dpkg -x lxc-android-config_0.161_all.deb /

( ignore link erorrs from lxc-android-config unpacking )

# stop ofono
# find /var/lib/ofono -name gprs -exec rm {} \;
# rm /var/lib/NetworkManager/timestamps
# reboot

If you have any problems with these steps, please feel free to ping 
myself ( awe ), Sergio ( sergiusens ), or Oliver ( ogra ) on #ubuntu-touch.

p.s. NOTE - image #281 had a regression which adversely affected NM's 
ofono code, so please don't test with it!
