ios 5.1 with xcode 4.2 for iOS development

I updated my iPhone to iOS 5.1. My operating system is Snow Leopard.
Now I need the sdk 5.1 to develop, with xcode 4.2.

Where can I download it?
Any suggest?

Solution: Downgrade to ios5.0 or update to Lion

You can't.

You need to update to Mac OS 10.7 Lion in order to get the latest version of Xcode with the 5.1 SDK.

The last installable version of Xcode on Snow Leopard will be 4.2. Apple really wants developers to keep up to date on everything, whether MacOS or iOS.

To get Xcode 4.2 on Snow Leopard to run code on a device running 5.1 you can do this:

If you have another Mac running Lion + XCode 4.3.1 you can copy the files from: 

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/5.1 (9B176)

to the equivalent place on your SL Mac: probably 

/Developer/Platforms/iPhoneOS.platform/DeviceSupport

and also copy version.plist from the Lion machine in the iPhoneOS.platform folder to the SL machine.

Re-start XCode on the SL machine and re-connect the devices and it seems happy enough.

[Edit: If you don't have access to a machine with Lion+4.3.1 you can get the files out of the 4.3.1 DMG which can be downloaded from Apple here: http://adcdownload.apple.com/Developer_Tools/xcode_4.3.1_for_lion/xcode_4.3.1_for_lion.dmg

then mount the DMG, Show Package Contents on the XCode icon and drill down to 

/Volumes/Xcode/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport to

find the files mentioned above.]

In steps:

  • Stop XCode on SL machine
  • Disconnect your iphone
  • Mount the Xcode 4.3.1 image (.dmg that you can download from Apple dev site)
  • Show package contentes of the Xcode 4.3.1
  • copy XCode/Xcode/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/5.1 (9B176) to <HD>/Developer/Platforms/iPhoneOS.platform/DeviceSupport
  • copy XCode/Xcode/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/version.plist to <HD>/Developer/Platforms/iPhoneOS.platform/
  • Start Xcode
  • connect your iphone and it should work.

    • If you want to stay on Snow Leopard, download the iOS 5.0.1 firmware of your device on this link : http://www.iphonefirmware.com/firmwares-download.

    And do a manual restore on iTunes.

    I did it today (March 8, 2012) on my iPad 2 and it works, Apple still seems to sign this iOS version.I guess not for a long time, so do it quickly.
