T-Mobile has joined fellow telecom providers Orange, O2 and Vodafone in selling the new iPhone 4 in the UK.
Carphone Warehouse and Phones4u will also stock the latest iPhone in their retail outlets at release.
Unlike the other service providers, however, T-Mobile will not be offering the new device at the time of release on 24 June.
The company said in a statement: "T-Mobile UK will launch the iPhone 4, the thinnest smartphone in the world with the highest resolution display ever built into a phone, in the coming weeks."
T-Mobile is yet to reveal exactly when it will begin selling the iPhone 4, nor has it revealed its prices or tariffs, but a spokesperson for the company has said that details will be available in a couple of weeks.
The iPhone 4, introduced by Apple Ceo Steve Jobs at the company's World Wide Developers Conference (WWDC) on 7 June, will begin shipping on 24 June, with pre-orders starting from 15 June.
