Several sites reported on speculation that Apple was going to upgrade the current 100-song limit on Motorola iTunes phones. This was based on images found in the latest iTunes binary indicating that the users phone could be upgraded: "Want more music on your mobile phone with iTunes? Upgrade now".
The celebration appears to be premature as the iTunes product manager clarified that "the upgrade screen exists for non-US customers, some of whom initially had caps as low as 25 songs, and brings their phones up to the 100-song limit."
