Unless you have a smartphone or a Sidekick, you probably CAN'T receive emails on your device. Most carriers in developed countries allow unlimited or high amounts of messaging, which includes MMS, but meter data sent via email. MMS is limited, but the device and the network usually decides the file limitations, such as filetypes and size. My carrier's MMS system automatically resizes photos when sending, significantly saving data. Even the iPhone downsizes images when emailed from the device! So its like a forced MMS system.
