4G: The Epic 4G is the second device on a U.S. network (the HTC Evo 4G owns the title of 'first') to boast 4G connectivity, making it capable of connecting to Sprint's WiMax network (where available) and enabling the device to reach peak download speeds of over 10 Mbps and peak upload speeds of 1 Mbps. In areas without 4G connectivity, the Epic will still operate on Sprint's 3G network. The iPhone 4 is limited to AT&T's 3G network.
Unlimited data: The Samsung Epic 4G offers unlimited data usage over the 3G and 4G network. New AT&T iPhone users and users who have opted to change their plans will be limited to the selected tiered data plan with no available unlimited data use option. The distinction should only be a consideration for heavy data users without frequent proximity to a WiFi network.
Operating system: The Samsung Epic 4G is an Android-powered device featuring Samsung's custom user interface called TouchWiz (version 3.0). The Android platform and TouchWiz include a number of differences, and depending on personal opinion, enhancements when compared to the iPhone OS -- perhaps most notably superior customization options and the ability to add widgets. Many users, however, prefer the simplicity and minimalism of the iPhone OS. The latest version of the iPhone OS also offers multitasking, although the multitasking capabilities as compared to Android (a seasoned multitasker) are still somewhat limited. Android users will also be quick to remind you of other Android advantages such a free turn-by-turn GPS directions, voice-to-text, the ability to install any application you wish without being limited to only approved apps, and more. Certainly, the differences are many (and beyond the scope of this comparison), and the choice between the two popular operating systems is one of personal preference.
Power: In the mobile phone food chain, both the Samsung Epic 4G and iPhone 4 are tops dogs. The Epic is equipped with an ultra-fast 1 GHz Hummingbird processor and 512MB of RAM. The Apple iPhone 4 has Apple's own A4 processor, which hovers around the 1 GHz mark as well, although Apple hasn't disclosed specifics on the processor. Both phones should offer relatively comparable speed and performance.
Keyboard: Of course, the Apple iPhone 4 boasts one of the best virtual (on-screen) QWERTY keyboards of any full touchscreen device. The Epic 4G, however, offers a fantastic physical slide-out QWERTY keyboard as well a virtual keyboard. Users preferring a physical QWERTY keyboard will likely favor the Epic over the iPhone.
Mobile hotspot: The Samsung Epic 4G can function as a 3G/4G mobile hotspot, providing the ability for up to 5 WiFi enabled devices to use the smartphone's internet connection simultaneously. The Apple iPhone 4 lacks native WiFi hotspot capabilities.
Display: The Samsung Epic 4G has a large and vibrant 4-inch Super AMOLED display with 480 x 800 pixel resolution. Because of its large display, the Epic is an ideal mobile device for movie-watching and web browsing. The iPhone 4 has a relatively moderately sized display (as smartphones go), but offers an impressive and industry best 960 x 640 pixels. As such, the iPhone 4 has many more pixels-per-square-inch than the Epic, making it a significantly higher resolution device.
Camera: Both the Samsung Epic 4G and the iPhone 4 have a 5-megapixel camera with autofocus and a single LED flash, and both are able to capture video in HD-quality at 720P. Each device also sports a front-facing camera for video chat, although the video chat on the iPhone is limited to WiFi networks.
