Just wanted to make a post here offering to share these. These are for the iPhone 4 only. For now I only have UK ones, but I'm happy to add other logos to this post if it proves popular enough. You just need to be jailbroken to use these with SSH access. No winterboard or any other theming tools required. Just SSH to the appropriate directories, then extract the zip files to that location. /system/library/Carrier Bundles/iPhone/O2_UK.bundle /system/library/Carrier Bundles/iPhone/Vodafone_uk.bundle /system/library/Carrier Bundles/iPhone/hutchison_uk.bundle I don't do requests, but as I said, if people send me logos I'll be happy to add more.
