The original iPhone is hugely successful because it's the first with a decent Data plan from phone operators
Errm, not quite. AFAIK, that honour goes to Blackberry where operators assigned a special tariff. Apple's innovation was that it was capable of making mobile networks share their revenue for participating in the whole iPhone thing - for the first time in the history of mobile phones, a VENDOR was calling the shots. That never happened before, and nobody else has managed since either.
Having worked inside telecomms and mobile operators, not only do I know that they make enough profit to become sluggish and wasteful (efficiency only shows up when money is tight IMHO), but to get them to share their gains with an external 3rd party that is not in the networking business is a feat that frankly made my jaw drop.
