CUPERTINO, Calif. >>Apple says the long-delayed white iPhone 4 will go on sale Thursday in the United States, United Kingdom and 26 other countries for $199 or $299 depending on the model.

Apple Inc. said Wednesday the prices are for phones purchased with a two-year contract from AT&T Inc. or Verizon Wireless in the U.S.

The black iPhone 4 went on sale last June. Apple had hoped to make the white phones available in July, then in late 2010. But it has said that the gadget was more challenging to produce than expected. In October, Apple said the white phones would be available in the spring.

Separately, Apple says the iPad 2 will go on sale in Japan on Thursday and in Hong Kong, South Korea, Singapore and eight more countries on Friday.
