Hi - usually it's 'any connection' with 'switch to WLAN when available' but tried it with Vodafone GPRS and same happens, but only when leaving a wifi network. The re-setting back to the original connection after receiving an MMS always works fine. So this is more of a handset issue handling multiple connections, not an fMMS issue. Also tried it named both with MMS and zMMS, but always goes to MMS connection. Good news is the only difference to my bill is that instead of the internet session showing as 'internet', it showed as 'wap' for the MMS connection - and zero cost, so thankfully recognised as an internet connection and not an actual MMS message and included in my bundle. Thanks again, Ian
