It's dilemma time: iPhone or Samsung F700? Vodafone's just announced it’s signed up the Apple baiter, which, unlike its US competitor, does have high-speed 3G data. And a proper keyboard, an auto focus camera and a memory card slot, we might add. Granted there's no flash memory on-board but a 4GB MicroSD (around £25 from your friendly local e-tailor) should start to make up for that.Samsung's also got its own new touchscreen interface, dubbed 'Croix' which looked splendid when we saw it from behind a Perspex screen at 3GSM but that's as close as we were allowed to get.There's been a few sneaky spec changes since then – the 5MP camera has become 3MP and the HSDPA top-speed has been sliced from 7.2Mbps to 3.6Mbps – but that still beats the 2MP iPhone with its measly EDGE data, gasping for air at a frankly poor 0.4Mbps top speed.If Tuesday's Apple announcement is what we think it is, we could see these two giants fighting out within mere months. Choose carefully, gadget fans.EssentialsSamsung F700Price: TBAOn sale: TBAContact: SamsungRelated stories:UK iPhone announcement: 18 September?Live Stuff: 3GSM: Samsung's mobile treatsSamsung stunner is a real iPhone killer
