Hey!
It would be really neat if a MMS is saved to the outbox when you press send and are out of service. When Im out of GPRS/Edge/3G coverage and have created an MMS, I need to stay in Swirly to avoid it disappearing. It's particulary annoying when you have written a long text message in the MMS.
So: Make an option like "save draft" availible, OR save MMS to outbox when the errormessage "Failed to send MMS" appears.
