Many thanks, don't know how I missed that in the first post. Searched for those sort of terms too!

Managed to send myself a picture message successfully too!

Thanks for such a great piece of software. Only two things could make this better now, integration with Conversations and an option to send a photo via MMS directly from the photo app (via the share menu).

Once again, thanks for you help and a great app.

[Edit] It now seems that my default T-Mobile connection has been deleted! Guess I'll have to do a restore from a backup to fix it!
