Best Buy Mobile today announced that it will begin pre-sale of the iPhone 4 tomorrow, June 15. Pre-sale orders can be placed at any Best Buy or Best Buy Mobile standalone store nationwide. The iPhone 4 will land in Best Buy and Best Buy Mobile stores June 24.

Consumers who purchase the iPhone 4 at Best Buy will avoid mail-in rebates.

“Adding the iPhone 4 to our stores alongside other great smartphones like the HTC EVO from Sprint and HTC Incredible on Verizon, gives customers a great opportunity to view each side-by-side and get the mobile phone that works best for them,” said Shawn Score, president of Best Buy Mobile.

The iPhone 4, which was unveiled in a June 7 keynote by Apple CEO Steve Jobs, is the company’s fourth revision of the original iPhone. The phone comes in 16GB and 32GB models, which sell for $199 and $299 respectively, with a two-year contract.
