There's no denying that the iPhone 4's FaceTime is a tasty new feature. But let's be honest, Apple's video calling is limited in its use right now, being as it wil only operate over Wi-Fi and only with other iPhone 4 users. That's not exactly mass market, no matter how popular the new iPhone proves. That's where Skype comes in.According to Pocket Lint, Skype has made it clear that it 'would welcome the opportunity to work with Apple', when it comes to enabling Skype video calls on the new iPhone 4. Obviously it would, because that would do Skype no end of commercial favours.'It's clear to us at Skype that mobile video will become increasingly important to our customers in the coming year. We would welcome the opportunity to work with Apple to bring mobile video calling not only to our many millions of Skype users on iPhone around the world, but also to the countless more making video calls on desktops, TVs and other connected devices', said a company spokesperson.It does make sense. After all, if the iPhone can contact, via video, anyone on just about any connected device, surely this is going to shoft more Apple smartphones? If it doesn't, FaceTime will remain just a show off feature in a niche market.
