I have an iPhone 4, my wife has a jailbroken iPhone 3G on Simple Mobile (T-Mobile's network). She's able to send and receive MMS messages, but images that are taken on my iPhone are flagged as too large and she receives a message that she has received an image from me but it has been blocked due to size.
Older phones and other limited plans have this implementation, so this question should be useful to others.
Is there a way to change the size of images when sending them via MMS like you can when emailing a picture on the iPhone?
If not, how can I work around this?
