If there is a low cost iPhone 4 with reduced memory (more than enough) and the same screen size but simply lower cost components, the retail price of the phone will drop, encouraging sales similar to iPhone 3GS (26 months after deployment). It will however in no way reduce the amount of the plan cost the carrier shares with Apple. The profits to Apple to make a viable low cost unit that stays within their hardware margin targets (30%+), is extraordinary. Airtime plans range between $40 and $100 a month over 2 years postpaid or $960-2400 of which Apple captures just under 30%. That allows them to price the unit below "target price". If the unit did not force an unnecessary voice plan, but instead relied on VoIP and had a data only plan as the unit is fully capable of, it might have a $15-$40 a month plan, much less revenue sharing, and a retail price triple the current level.
Someone has to pay for an entire computer in your hand with a large back end network. Currently it is voice plan users. Try to buy an iPhone without one. Good luck.
