Wouldn't the other phones have it because there isn't the App Store and the control over the apps like this? IN this case, AT&T can tell Apple "no way in h*&&" will you let that get approved as is.If it is a bandwith issue, then why do Blackberries (with as many and likely a lot more units out there) have 3G sling? I know that AT&T would rather have people buy Blackberries (I am sure Apple takes a bigger cut than RIM), but why would Apple go along? All Apple has to say is "you have to give us equal treatment"(why still no tethering too?). They are intentionally making their competitors more attractive by denying some of the coolest features other phones have (and not because the iPhone CAN'T do these things).
I was skeptical of it being approved at all because of the bandwidth issue...
