Thanks to Engadget we now have a spec comparison between the iPhone 4 and the older model iPhone 3GS.

iPhone 4

iPhone 3GS

Apple's finally announced the iPad (Apple Tablet). It is perfect for tasks like browsing, email, photos, e-books and videos. It's a half-inch thick and weighs just 1.5 pounds (680g), with a 9.7-inch capacitive touchscreen IPS LCD display and it's running a custom 1GHz Apple "A4" chip developed by the P.A. Semi team. The 10-hour battery life and a month of standby is quite exciting.

There will be devices with 16, 32 and 64GB. All iPads will get a 30-pin Dock connector, a speaker, a microphone, Bluetooth, 802.11n WiFi and optional 3G, as well as an accelerometer and a compass. There's also a keyboard dock, which connects underneath in the portrait orientation. iPad supports up to 1024x768 VGA out and 480p composite out through dock adapter cables. There is a camera attachment kit that lets you import photos from your camera over USB or directly through an SD reader.

The device is managed by iTunes, just like the iPhone and iPod Touch. iPad can run iPhone apps: either pixel-for-pixel in a window, or pixel-doubled fullscreen. Developers can also target the new screen size using the updated iPhone OS SDK, which is available today.

The 3G version runs on AT&T and comes with new data plans: 250MB for $14.99 and an unlimited plan for $29.99 a month contract-free. Activations are handled on the iPad, so you can activate and cancel whenever you want. Every iPad is unlocked (!) and comes with a GSM "micro-SIM".

The price starts at $499 for 16GB, 32GB for $599, and $699 64GB. Adding 3G costs a $130 per model, so the most expensive model (64GB / 3G) is $829. The WiFi-only model will ship in 60 days, and the 3G models will come in 90.

UPDATE: The 3G version will also have A-GPS.

Next generation iPhone might have support for WiFi 802.11n. A recent Apple job posting shows that such software support might come soon:

Implementation of 802.11 a/b/g/n & related specifications.

802.11i/802.1x Security protocols

Good understanding of wireless RF technologies & co-existence issues of 802.11 PHYs with other Wireless interfaces like Bluetooth.

The addition of Wireless N capabilities and support are quite logical. Hope to see iPhone 4G soon.

Over the weekend, hints of several additional features for the next-generation iPhone were revealed. Among them was the discovery that text strings in the iPhone OS 3.0 software reference a new Broadcom wireless chip, BCM4329, which supports 802.11n wireless connectivity. In digging through the specs for the chip, 9 to 5 Mac has discovered that it also supports both reception and transmission of FM radio signals. The finding, however, doesn't mean that Apple will necessarily enable these features in the new iPhone.

The specs are taken from apple.com and htc.com.
