MMS' not being sent correctly
Just after a bit of advice if at all possible...... I'm currently having trouble sending MMS messages & am hoping some clever, techy person may know what the problem may be & how to solve it.
I have an iPhone 3G running OS 3.0. The phone is originally from the UK (on o2), but I am now living in Australia so it's jailbroken & unlocked - currently using a Telstra SIM card.
Pretty much everything on the phone works fine apart from the MMS. I load a pic & send which all seems to process fine, but the recipient never receives the message. I have tried sending messages to people on various networks here in Oz, as well as people back home in the UK & no one seems to receive them.
I have contacted Telstra customer support, but they are next to useless! I've done the usual reset of network settings & amending the cellular data APN to "telstra.internet", as suggested by Telstra themselvfes, but I'm still not having any luck.
Any thoughts/suggestions, would be much appreciated! Thanks!
