The Pre has been positioned as a prominent challenger to the iPhone, and that’s reflected in its launch date of June 6, just two days before the beginning of Apple’s Worldwide Developer Conference, which is expected to feature more in-depth information on the new iPhone OS 3.0 software. The other big question circling the Pre has been pricing: would it be competitive with the iPhone? Sprint now says the Pre will sell for US$200, though, as with the iPhone, you’re required to sign up for a new two-year service plan at the time of purchase. There’s another catch as well: that price is after a $100 mail-in rebate, bringing the total at time of purchase to $300.
