Instinct will cost $129.99 when released on Friday. That compares with $199 for the cheapest model of the new iPhone, which goes on sale July 11 with AT&T Inc. as the carrier. It has many features with the new iPhone, including access to a fast wireless data network and a GPS receiver. Sprint was unusually involved in the phone's development, and plans to promote it heavily. The cheapest monthly plan for the Instinct will cost $69.99, which ends up closer to $80 with taxes and fees. The cost for two years of service is then about $1,900.
