The iPhone 4 meta-post

I'm planning too many iPhone 4 posts at the same time. It's unlikely they will all be published, so I'm condensing them into this giant post.

Comparison with iPhone 3GS
Maybe I'm biased, but I want to believe the iPhone 4 is the best iPhone ever. Apple itself claims the iPhone 4 is the biggest leap since the original iPhone. I think it has many improvements over the 3GS, which was only an incremental upgrade over the 3G.

	3G to 3GS	3GS to 4
Form factor	Unchanged	New design. Thinner, glass front and back.
Speed	Twice as fast	Unstated
Battery	Longer battery life	40% more talk time
Input	Compass	Gyroscope, 802.11n
Screen	Oleophobic coating	High resolution, IPS, vacuum laminated
Camera	Added autofocus	Added flash

FaceTime

I've confirmed that FaceTime calls are free. It's quite smart - it rotates automatically, even upside down! However, here are my suggestions:

• Enable the video light
• Enable audio only calls - this is like free phone calls/Skype
• If you call someone who isn't on WiFi, you aren't told that the person isn't on, you just keep trying to connect. There should be a way to tell you "person not online" or something.

More nice touches:

1. Use as a scanner. I took a picture of an A4 document and was able to read the text in the picture. Of course, this depends on the size of the text. I wonder what the critical camera resolution is to do this.
2. They've somehow incorporated a universal zoom feature for those who can't see small text. (enable it in accessibility options)
3. You can add someone's address from Maps, instead of typing it in.

Suggestions

• Hide keyboard in Messages
• Allow users to change SMS and email ringtones already, it's quite irritating having 2 iPhones with the same email tone
