Apple and T-Mobile resolved an iPhone 17 pre-order issue before it caused significant problems.

If you didn't get the right value for your T-Mobile trade-in with an iPhone 17, 17 Pro, 17 Pro Max, or iPhone Air pre-order at Apple, you might want to check your email for a fix right now.
Many early buyers of the iPhone 17, 17 Pro, 17 Pro Max, and iPhone Air were promised discounts of $800 with qualifying trade-ins on certain T-Mobile plans. However, initial orders displayed much lower values for devices in very good condition, leading customers to fear high costs for their new phones.
If you did not cancel your order, check your email for a message from Apple, which many Redditors have shared and confirmed over the past day. The error was noticed and will be corrected quickly, as anyone familiar with Apple and T-Mobile might expect.
For example, if you received an instant credit of only $200 for your trade-in in "good condition," expect to receive the remaining amount up to $800 as T-Mobile bill credits, starting within the next three billing cycles. This may not be ideal, but trade-in deals can be complex and take time. It is good to know that everyone will eventually receive what they are due.
The error from Apple and T-Mobile seems to have affected those on Magenta's expensive Go5G Plus plan. If you are not on that plan, you likely did not experience panic this past week, but you may have received a smaller discount than $800.
Alternatively, you could have pre-ordered your new iPhone from T-Mobile instead of Apple. The "Un-carrier" is expected to continue offering deals for these devices even after the pre-order period ends today.
