AT&T has confirmed that it will support MMS messing and tethering(use your phone’s #G connection with your computer) for IPhone 3.0 later this summer.
An AT&T spokesperson said, "We [need to] complete some system upgrades that will ensure our customers have the best experience with MMS. These upgrades are unrelated to our 3G network. We plan to offer a tethering plan, but don’t have an announcement to make at this time." Data plan rates will remain the same at $30 per month for unlimited data. For new and qualifying customers, the iPhone 3GS will cost $199 and $299 for the 16GB and 32GB models, respectively. If you are not currently eligible for an upgrade but still want iPhone 3G S, early upgrade prices are $399 (16GB) and $499 (32GB). No-commitment pricing: $599 (16GB) and $699 (32GB).
So, as of now, MMS won’t be working IPhone 3G with OS 3.0. It has taken Apple 20 months to integrate MMS with the IPhone.
Its now to see whether MMS will work both ways, that is, with the sender and the receiver. I’m curious to know, if only the sender upgrades to OS 3.0 will the receiver, who hasn’t updated to OS 3.0, would be receiving the MMS?
