AT&T has announced details of its upgrade pricing scheme for the iPhone 4. According to the company, new customers, upgrade eligible customers, as well as any iPhone customer who would be upgrade eligible for a discounted device by the end of 2010 will be able to purchase the iPhone 4 at the $199 and $299 price points with a new two-year agreement. AT&T customers can instantly check their upgrade eligibility dates by calling *639# from their iPhones; several iPhone 3GS users, including at least two iLounge editors, have reported that they are already listed as being upgrade eligible. For iPhone customers whose upgrade eligibility date is some time in 2011, AT&T is offering early upgrade pricing of $399 for the 16GB iPhone 4 and $499 for 32GB units, again with a new two-year agreement. Finally, customers who choose not to sign a new agreement are eligible for AT&T’s no commitment pricing, which is $599 for the 16GB model and $699 for the 32GB model. Apple will launch the iPhone 4 on June 24; pre-orders open on June 15.
