Apple has opened pre-orders for the iPhone Duo, and major U.S. carriers are already posting promotional offers for customers who buy through their networks. Below is a concise roundup of the best deals currently available from AT&T and T‑Mobile, with eligibility requirements and how discounts are delivered.
iPhone Duo deals at AT&T
AT&T is offering up to $1,200 off the iPhone Duo with an eligible trade-in. That maximum discount requires a trade-in valued at $230 or more and activation of a new line or upgrading an existing line; the credit is applied over the course of 36 months on your AT&T bill.
Customers switching to AT&T can receive up to $800 toward paying off their current device balance, and AT&T is also offering $200 off per line when ordering the smartphone online. AT&T’s plan-tier breakdown for trade-in credits is as follows:
– Up to $1,200 off: requires AT&T Premium 2.0 plan or higher and a trade-in value of $230 or more

iPhone Duo deals at T-Mobile
T‑Mobile is advertising up to $1,000 off the iPhone Duo with any‑condition trade-in when you purchase on an Experience Beyond plan; the discount is delivered as bill credits over the course of 36 months.
T‑Mobile also lists additional offers tied to its plan tiers: customers on the Experience More or Experience Beyond plans can get up to $830 off with a trade-in, and customers adding a new line on most other plans can get up to $730 off. All of these T‑Mobile credits follow the same 36‑month payout schedule.
