Here installed 0.4.0-1, tested with a self sent MMS

operator H3G Italy, the 'proxy trick' works, so no new APN to set but just inserted proxy datas enabling it and then disabling it leaving data there
sequence worked flawlessly (i'll add to the wiki)
- before the test, standard data connection open + connection to galk and skype account and application manager downloading in the background
- started and used fmms to compose a mms + image
- fmms sent the message without complaining anything
- ten minutes after, received sms push, appmanager still downloading (playing with new QT demos...)
- fmms launched itself and connected to acces point via proxy - download of application manager suspended as expected and message 'not possible to connect to some services' or whatever is the translation in english appeared
- mms downloaded automatically
- fmms showed the mms
- application manager resumed download and skype+gtalk account restarted

sidenote: exactly after having received the sms push, the phone rang and I had a phone talk via speakers looking how everything was going on in the background reading the messages on the screen

I honestly think frals made a great job, thank you!
