I recently reinstalled OSX. It has been a pain rounding up all of my certificates, etc, but I finally am back. However, when trying to install an app on either of two iPhones 3G's I have, they both say:
Software version: 4.2.1 (8C148) | XCode cannot find the software image to install this version. | Could not support development.
What is going on? Both iPhones list themselves as up to date in iTunes, and iOS developer's center only lists 4.2 as the available SDK.
EDIT: I do have a paid membership, and I have recently had test apps installed on both of these devices.
UPDATE: I removed all 3 ( the 2 included ) of my devices from the provisioning portal, and deleted them from the organizer, closed XCode, detached device, restarted, plugged in device, no luck.

Tap Settings > General > Profiles or Profiles & Device Management. Under the "Enterprise App" heading, you see a profile for the developer. Tap the name of the developer profile under the Enterprise App heading to establish trust for this developer. Then you see a prompt to confirm your choice.
Xcode 12.4 includes SDKs for iOS 14.4, iPadOS 14.4, tvOS 14.3, watchOS 7.2, and macOS Big Sur 11.1. The Xcode 12.4 release supports on-device debugging for iOS 9 and later, tvOS 9 and later, and watchOS 2 and later. Xcode 12.4 requires a Mac running macOS 10.15. 4 or later.
Yes. It is possible to build an iOS app without owning a physical iPhone or iPad. This is possible through using the iPhone and iPad simulators in Xcode. There are also third-party simulators that you can use to develop your iOS application.
I just got this error with Xcode 4.0.2 and an iPhone 3G running 4.2.1 (the final 4.x allowed on a 3G). I restarted Xcode and it went through the process of collecting debug information, then gave me a green light. Other answers here say that you may also need to quit iTunes for this to work.
Conclusion: Try restarting Xcode. Quit iTunes first if it was open.

Classic ;-)
find your iphone and press "Use for development"
As Jacob said: try adding / removing your device as well
If you still get this error you have an out of date XCode
