Apple confirmed the rumor that iTunes would be the only way for users to buy and download iPhone applications. Customers will be able to browse and search for applications, some of which will be provided for free. Developers will get 70% of the sales revenue paid monthly and with no credit card fees. Restrictions, however, have been placed on the type of applications that can be sold: no pornography, nothing illegal, no bandwidth hogs, and nothing that could cause “unforeseen” problems. VoIP will also not be allowed over cellular connections, just WiFi.
