I answered all the questions that I could.
MacRumors.com
How does it (not) handle Flash?
Any other websites?
It's working fine on the MacRumors forums for me, just as if I'm using my browser on a laptop or desktop Mac. For flash, it just says you don't have flash installed.
I've had Safari crash a couple times so far. The iPod feature seems to crash a lot when I'm listening to music while browsing the web.
It starts in about 20 seconds.
Surprisingly it does not seem to scratch at all.
How is using the virtual keyboard?
After two days of typing on it I'm getting pretty fast with the virtual keyboard, much faster than the regular keypad that I had on my old phone.
How was the installation experience with importing all the stuff
It was like importing all your music and videos to an iPod.
How easy is it to set up mail, contacts etc.
It was surprisingly easy to set up mail to work with my Gmail account. Contacts are easy to set up also.
Do you have any scratches or smudges yet?
Well I have no scratches, but fingerprints are showing on the screen when it's off. Unless you look for the fingerprints when your using the iPhone, you aren't going to notice them.
How's the screen in the sun?
It's pretty good, I was at the beach yesterday and I could easily surf the web and watch videos on the screen in the sun.
How good is the multitouch?
I really like multitouch, this is by far the best touch screen I've ever used.
Can the keyboard switch between qwerty and alpha numeric when typing? like on the wii?
There is a button that shows up on the lower left of the keyboard to switch between qwerty and symbols, etc.
EDGE bearable? Benchmarks?
I'm using a FiOS internet connection right now, but I still find EDGE to be bearable. I don't have any benchmarks though, if someone could point be to a non-flash based benchmark I'll try it out.
Which WIFI Encryption is supported?
It fully supports my WPA encrypted WIFI network.
How well does it find signals?
It's decent, it finds some WIFI networks that my MacBook Pro can't find and vice-versa, so they are comparable.
For the super fast cell phone texters, can the keypad keep up with quick presses of keys, or is there a laggy delay before the input is displayed? If you've ever used a Motorola Razr, you're familiar with this lagginess.
Yes, this sometimes happens when you are typing in a text field on a website while it's still loading. As soon as it's done loading, the lag disappears.
Can you save websites for later view?
While you're visiting a website, you can press the home button and it will save what websites you are viewing.
How does it feel in your hands, slippery, easily droppable?
It does feel a bit slippery, but it doesn't feel like you're going to drop it. It feels really nice in your hands.
I love the interface, it nice and easy to use, while holding a lot of features.
Can you input text in landscape mode? (only in safari)
You can only do this in Safari unfortunately.
How long does it take to charge?
A long time, I didn't exactly gauge how long it took, but it was more than my old 60GB iPod took to charge.
It's great, it lasted me almost all day yesterday while I was at the beach. I surfed the web, watched a couple videos, listened to music and it gave me a good 9-10 hours.
I found the headphones surprisingly good for calling and very convenient.
Can you listen to music on speaker?
Yes, you can, and it sounds decent.
How much free space is there on 4GB or 8GB?
There was 7.27GB of free space on there when I first synced the phone.
