The Blackjack will use a battery in a day and you always have the option to carry the spare battery if you are going to be on the internet a lot. You have the 3G capability that blows EDGE out of the water and the ability to use micro sd for expanded memory.
Still better than what the iPhone will offer to start.
I gave up on the tiny battery and just use the bigger one. Sometimes if the battery dies and I recharge it, it will still say that the battery is almost dead until I pull the battery out and reset it. Just annoying, that's all.
