With its squared edges, slim chassis and chrome silver trim, Apple's design team has revamped the iPhone 4. It's still definitively Apple though and remains gorgeous. The 3.5-inch display has a tempered glass coating that should help prevent any scuffs and bumps.
Apple's Retina Display technology promises a resolution of up to 326dpi. To put this in perspective, it's as clear as reading a book, with detail so fine no matter how far you zoom into a piece of text.
The iPhone 3GS's touch-screen was great. The iPhone 4's is even better. Finger swipes are as feather-like as ever, while the auto-correct facility is so good you'll be banging out passages of text on the virtual QWERTY keyboard without pausing for a beat. With a powerful 1GHz A4 processor, the iPhone 4 can now multitask, with the ability to run multiple applications without having any detrimental effect on the running of the phone. However, it's worth noting that some applications while remaining open, will simply pause rather than run continuously in the background.
Unlike the Android range, you can't enter the first few letters of a friend's name to bring up a list of possible contacts. Instead you'll have to type the full number or search via the phonebook.
One of the iPhone 4's key features is FaceTime calling, which is basically Apple's take on video calling. However, whereas video calling has always been a little, well "eurgh", FaceTime is near flawless (the one downside being that you can only speak/see other iPhone 4 users). There's also an improved five-megapixel toting camera that not only has an LED flash, but can also shoot movies in 720p HD.
Resembling something akin to an iPhone 3GS, the Samsung Galaxy S has a tempered glass back with a discreet chin that helps elevate the camera when laid on its back. However, it's the large four-inch display that dominates proceedings.
The iPhone 4 may have its Retina Display technology, but the Galaxy S has its own Super AMOLED display that simply sparkles in every capacity. Menu icons are as crisp as we've ever seen and video whether, side-loaded, played via YouTube or shot yourself is excellent.
The capacitive touch-screen is one of the most responsive we've ever encountered. There is a D-Pad and a touch-responsive menu and back keys, but it is the touch-screen that will be your main point of control. It's a shame there's no dedicated camera button, instead having to get there via the menu system, however, the fact that the Galaxy S runs on Android 2.1 means you'll be able to enjoy multi-touch, that old pinch and pull zooming action Apple has been such an advocate of. The pace of the Samsung Galaxy S is impressively quick thanks to the formidable ARM Cortex A8 1GHz processor.
Gaining a sat nav fix can prove a tricky affair, despite its assisted-GPS credentials.
Swype is an innovative way of typing text by dragging your finger from one letter to another. It works a treat and could save you some vital seconds, even if it has a detrimental effect on your grammar. The fact that the Samsung Galaxy S is DLNA compatible means you'll be able to play movies, music and project photos saved on your phone onto any DLAN certified TV or computer.
Putting the Apple iPhone 4 head to head against the Samsung Galaxy S is too tough to call. You won't be disappointed with either handset and both will long be considered phones of the year. It may simply come down to whether you want to follow the crowd and go for the iPhone 4, or opt for the more cult-esque Samsung Galaxy S. We've played with both and still can't make up our minds.
