Let the hive mind of Engadget get that for you.
"I own an iPhone 3G and I'm looking for a decent speaker / alarm clock for it. I am going to listen music in a mid-sized room, so I want nice quality speakers with solid bass. I also want to use it as an alarm clock, so it would be great if there is such a feature. The price can be low-mid to mid-high range. I was looking at the Klipsch iGroove SXT; it's powerful, slick and the reviews are good, but it doesn't have an alarm clock feature. It's no deal breaker if I can set it up from the iPhone, but I'm not sure. Thanks!"
The thing is, I'm a little nervous about the keypad still. This isn't what I wanted to see.
Instead of telling me you won't make that many mistakes, they tell me "You will make TONS, and don't even try typing with two thumbs for atleast a week. But when you make typos, the iPhone will try to fix it."
I'm not sure I feel comfortable having the iPhone fix all my typos when sending an email to my boss.
Not sure I like the "sent from my iPhone" signature either.
I agree. I'd love to see some examples of a person walking down the street typing two-handed with as much ease (or more, according to Apple) as the Treo and Blackberrys give. Although that might be hard to choreograph. I think most people would be too afraid to look away (since you can't due to the lack of tactile-ness of the keys). Imagine being the first person to drop your new $600 phone on the pavement.
I think you can be 99.9999% certain that you'll be able to edit the signature.
