Completely agree, especially considering that "use email" is entirely useless for receiving MMS messages. Nor to mention the sheer idiocy of having to grab a pen and paper, writing down a convoluted message ID and password, and having to go to a web site in order to view them. They got AT&T to do MMS....it'd have been nice if they could get AT&T to maybe work on some sort of method that it would get an MMS, convert it to an email, and email it to the iPhone....or something!
Also, the restore as a matter of course will wipe out your SMS messages...it is completely wiping the phone's memory. Just sync the phone with iTunes beforehand, and sync afterwards and all is good. I've still got messages on my phone from the day I bought it, and I've restored it several times.
Honestly, I hope that they're not going to tie the phone more to Leopard or .mac.....the iPhone as it is for the most part is an excellent cross platform device, and there'd be a LOTTA hollering from the not so small Windows based iPhone user demographic. But I guess we'll see. Honestly, I don't see them as doing anything with MMS...my guess is that bug fixing and newish features like iTunes wifi and the Starbucks thing are a LOT more important to them right now than writing an MMS app.
