The iphone on Verizon will not be on the 4g LTE network yet. So these first phones will have a lower data speed than what is available to iphone/AT&T customers. Apple didn’t feel they could bring a 4g phone forward right now…and with 3 years of customers lined up to use any network other than At&T they didn’t have to.
They are playing it safe because many 4g users report very slow speeds once they step out of the 4g coverage area.
Once Verizon spreads a solid 4g system around,
you can be sure Apple will introduce iphone 5.
The real trade off is no phone/data multi task which iphone users have gotten accustomed to
but still a number of Android phones don’t multitask either.
Also Apple claims a text delivery “shouldn’t” interrupt a phone call.
I’ll wait for the user reports on that. lol

The reason Apple launched with AT&T then Verizon is really pretty simple.
AT&T and Verizon are the most expensive carriers in cell. They can afford to pay Apple what is estimated as $12mo from each iphone service contract. You’ll notice Sprint and TMobile who charge a lot less for service can’t pay as high or possibly any revenue sharing fees back to Apple.
