The biggest question is how well is 4G represented in your area? If it's widespread, then go 4G. If it's not widespread yet, then stick with 3G. I bought an iPhone 4S in December, and the speed is fine for me, and decided to not wait for a 4G iPhone offering, which I'll upgrade to at the end of next year.

The $30 data plan is probably all you'll ever need. You can certainly use Wi-Fi with your phone and will NOT charge against data time. Someone else will have to talk about streaming Netflix on 3G/4G as I've only done a few youtube videos here and there.

Considering that 4G isn't available to most of the country yet, you could get away with buying a 3G phone now and upgrade to 4G in 2 years when it's more prevalent. However, if you have the cash, and you have good 4G coverage, wouldn't hurt to jump on the bandwagon so to speak.

The only downside to Android phones I've heard is pretty poor battery life. A co-worker of mine has a Sprint EVO 4G and he's charging it twice a day.
