The iPhone has traditionally been plagued with dropped call issues – that seems to have been remedied in the latest version, which is lucky, as people were about to lose faith in Apple.
However, somehow Jobs' lot managed to let a big problem slip through the net: holding the iPhone 4 in your left hand will force signal to drop dramatically. We haven't encountered any dropped calls because of it, but it's a poor show.
Call quality is good thanks to the noise cancelling microphone though – and FaceTime is there if you like living in the early part of the millennium.
The Desire loses one key feature from the Nexus One in a separate noise cancelling microphone – although that does mean it's £5 a month cheaper on contract.
Call quality is only average as a result – not poor by any means, but get caught on a noisy street and you'll struggle to be heard.

Like the Desire, there's no noise cancelling here – call quality is improved simply because the device is longer than most others thanks to a 4-inch screen.
Other than that it's the same basic experience – you get a fun beepy sound when calls are connected, the buttons are nice and easy to hit, and you'll feel pretty chirpy about the whole thing to be honest.
