iPhone Rate Plans Unveiled

Apple has published two PR providing additional information regarding iPhone Service Plans.

iPhone customers will be able to choose from three simple, affordable service plans when iPhone goes on sale on Friday, June 29. All three plans include unlimited data, Visual Voicemail, 200 SMS text messages, roll-over minutes, and unlimited mobile-to-mobile calling. In addition to a one-time activation fee of $36.00, customers can sign up for a new two-year service plan with AT&T for a monthly fee of $59.99 (for 450 minutes), $79.99 (for 900 minutes), or $99.99 (for 1,350 minutes). Family plans are also available.

In addition, one can purchase the 4GB model for US$499 or the 8GB model for US$599 then directly activate its account via iTunes:

When they purchase an iPhone, customers can use iTunes on a Mac or PC to activate their new phones in the comfort and privacy of their homes or offices instead of waiting for activation in a store. With iTunes guiding them through the simple steps of choosing a service plan, authorizing their credit, and activating their iPhone, they can complete the activation process in minutes. Following activation, new iPhone customers can again use iTunes to easily sync their phone numbers and other contact information, calendars, email accounts, web browser bookmarks, music, photos, podcasts, TV shows, and movies with iPhone.

One can now understand with such price and conditions, why Apple is still negotiating with key European carriers to set the best offer for all parties (Apple-Carrier-consumers).
