iOS 4 device compatibility - can your iPhone and iPod touch be upgraded?

During yesterday's WWDC 2010 keynote, Steve Jobs announced that iOS 4 will be a FREE update for all devices, and the iPhone and iPod touch version will be released on June 21 (iPad version is still slated for fall). The main features include multitasking, folders, spellcheck, unified inbox with threaded messages, iBooks, Bluetooth keyboard support, and custom wallpaper. (Be sure to check out our iOS 4 preview for more details!)

iOS 4 is available for the iPhone 3G, iPhone 3GS, iPhone 4, and the 2nd and 3rd-generation iPod touch. On the other hand, the original iPhone 2G and 1st-generation iPod touch will not be able to upgrade to iOS 4, and as with every big software release, some devices will not get all the new features.

Multitasking, custom wallpaper, and Bluetooth keyboard support are only available for iPhone 4, iPhone 3GS, and the 3rd-generation iPod touch.

In the past, iPod touch users had to purchase big software releases for $9.99. Not this year. iOS 4 is a FREE upgrade for iPod touch. This is huge news for our iPod touch wielding users.

If you use an iPhone 3G or 2nd-generation iPod touch, do any of these missing features entice you to upgrade? If so, do you plan to go big and upgrade to iPhone 4; or do you upgrade to the iPhone 3GS at the new amazingly low price of $99? iPod touch users, are you thrilled to be able to upgrade for free, or do you believe it should've been free all along?
