While AT&T and iPhone 4 newcomer Verizon seem set to continue their own war of words ahead of the handset's launch onto a second US network on 10 February - it looks as if the chaps in Cupertino want everybody in the Apple family to get along.

This latest Apple iPhone 4 commercial shows an AT&T iPhone 4 and a Verizon CDMA iPhone 4 side-by-side, dancing in tandem to "An der schönen blauen Donau" ("On the Beautiful Blue Danube"), a waltz by the Austrian composer Johann Strauss II.

The message from Apple is clear - it's the same phone on either network, at least in terms of performance.

The American public will be the judge of whether the network speeds prove to be so coherent though.
