I’m looking at upgrading my development iPhone 3GS from iOS4.3.5 to iOS5. Now that Apple even rejects apps that use the older SDK and contain an iPhone 5 launch image, I see no need to keep my iPhone 3GS on iOS4.
Even though the latest s/w for iPhone 3GS is iOS6, will an upgrade to iOS5 be successful through the server verification. I ask because I tried to restore in a similar situation previously on a different device (and different iOS versions) but it wouldn’t let me so I had to upgrade to the latest compatible version of iOS.
Success/failure stories would be much appreciated.
Thanks,
James
PS. this may not be a techy question, but as a community of developers, this seems to be the best place to ask!
Apple no longer signs iOS5 meaning that you can’t restore to iOS5 unless you have previously saved the SHSH blobs either in Cydia or with a tool such as TinyUmbrella.
