Tesco Mobile has become the latest operator to confirm that it will offer the iPhone 4 from 24 June.
The retail chain has yet to announce any tariff details or handset prices, but customers can register on the Tesco iPhone site to receive more information.
Tesco has been offering the iPhone 3GS on pay-as-you-go and monthly options since December 2009.
Apple announced prices for the SIM-free iPhone 4 yesterday. The 16GB version will be available for £499 and the 32GB version for £599.
Virgin Mobile is the remaining major network which has yet to disclose whether it will offer the iPhone 4.
The operator is in talks with "a number of companies", including Apple, according to a Virgin Media spokesman. However, he could not confirm when the company will make an official announcement.
