You really think they wont accept it, after MS and the browser ballot. Opera are just waiting to sue Apple, but more to the point, its a better browser and really proves how far behind Apple are compared to Opera
As much as I love Apple for their engineering and quality apps, this was always going to happen from the moment they failed to draft out proper development rules for their apps. Their silly early on API restrictions only served to hurt themselves and developers early on until they opened up API's later.
I hope something is done because Android is gaining pace and the other OS's have a lot more going for them right now.
It definitely happens with normal handset usage as well. I assume they are re-encoding images with increased compression and caching them on their own internal servers.
They used to charge for the desktop browser and they charge you for the Wii browser (I haven't checked in awhile so that might of changed). So they could charge for this as well.
Just downloaded it on my 3G. I'll try it properly on the bus ride to work in a bit.
