Whilst not an official O2 release, the MMS Photo Messaging app makes sending and receiving MMS messages on your iPhone that much easier.

The app is brought to you by the same people who released the web based service O2mms.net (now iphonemms.net).

The advantages with the native app are:

The app is a free download and it’s free to receive all MMS messages on your iPhone. When you get a MMS message O2 send you a text with a 4 digit pin number and a web address to view it. Instead of going to the web address you just launch the app, enter your 4 digit pin and the message will be downloaded onto your iPhone.

There is a charge for sending MMS messages which works out at about 35p/mms. Because this is not an official O2 release messages can’t be charged to your account but you simply order credits through the app itself and pay with Paypal.

The MMS Photo Messaging app is available to download from the app store.
