Though some may doubt Sprint’s commitment to Android, a quip from Sprint featured on InternetNews.com seems to disprove any speculation of Sprint’s infidelity to Android:

Sprint is engaged with Android — no need to question our commitment.

Thanks for the opportunity to share our perspective

Sprint is actively engaged with the Android community; for competitive reasons, we have not been specific about the timing of an Android phone from Sprint.

Sprint is a charter member of the Open Handset Alliance.

Sprint has a long history of leadership in working closely with developers to encourage them to create new content that can be offered on Sprint phones. The Titan platform is an example of Sprint’s work with the developer community. Our participation in the OHA and our work with the Android community is another example.

Though the source from Sprint is unknown, the comment seems very well-worded and confident about an upcoming involvement with Android.
