Well, here's a turnup.
Installed an i-On EXDL30 today from stock, didn't actually need the 'D' bit but wanted the 'L' larger case. Upgraded to latest SW (4.05) and whats
now in the SMS menu? TAP, TAP, more TAP, then right at the bottom, hang on... ETSI Protocol 1 with all the BT numbers pre-filled!
However, this model has an on-board dialler, so remains to be seen if you still get this when you plug on a digi02...
