Tried to answer as many as I could...
Other language options? No. I would imagine they will on the international versions.
Stable? any crashes? Not yet
Startup time? about 14 seconds
Instalock work? does it easily get triggered? I'm assuming you meant when you lock the phone so you have to slide your finger across to unlock....doesn't get triggered easily. You have to press very deliberately on the wake/sleep button
Can keychains be synced with your Mac? Not that I've seen, but when it synced my mail settings, Keychain had to allow Apple's device setting permission to get into my keychain
Screen seem scratchable? Not unless you grind it into gravel. It does smudge a lot
Speaker quality?Kind of soft. Have to turn up volume
Background noise with headphones/mic?Similar to iPod
How is using the virtual keyboard?Found it much easier than a Blackberry. Much, much easier...right off bat
How was the installation experience with importing all the stuff It pretty much does it all for you. Very easy
How easy is it to set up mail, contacts etc. Not to be smart, but how easy was it to set up your music on your iPod? It imports everything for you. No more spending an hour retyping your contacts into your tiny phone
Do you have any scratches or smudges yet? The back is nothing like an iPod. Much more scratch resistant. The screen smudges a lot. Quick wipe on your shirt or with the cleaning cloth cleans it off
How's the screen in the sun? Very comparable to a glossy Macbook screen. Very bright and no issues with the sun
How good is the multitouch? Works beautifully. Very accurate.
Does it support foreign language SMS, email and webpage? Only if the characters fit English style...like German. Chinese, Arabic, Russian, etc not supported. No special/accented characters.
Can the keyboard switch between qwerty and alpha numeric when typing? like on the wii?Not that I have seen
Network
EDGE bearable? Benchmarks?EDGE is like dial up, which is fine by me. Unscientific benchmarks: 5 seconds to load ESPN.com on my Mac (Wi-Fi DSL, 2 minutes to fully load on my iPhone with EDGE (1.5 min to load to the point where I could read it and browse. CNN.com on my Mac: 4 seconds. About 15 seconds on iPhone.
How well does it find signals?Cell...as well as any other phone. WiFi...as well as any computer I have used
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. Never noticed any lagginess. Keeps up with your inputs.
Can you save websites for later view? Yes. Bookmark support
Left or right hand issues? None at all
Form Factor
How does it feel in your hands, slippery, easily droppable? Hard to describe. Feels natural in my hand. Does not feel droppable
Interface? Beautiful interface. Like any Apple product, it works like you expect it to work. Makes any other cell phone interface look like crap.
Can you input text in landscape mode? only in safari
Comparisons
If you had service higher in oomph than EDGE (like 3g), can you say how slow it is in comparison? Jump off a building level, or tolerable? I think its tolerable. It is very comparable to dial-up..maybe a tad better. I don't plan on using this as my primary browser, definitely tolerable. I really don't see that much of a difference between this and my friend's Blackberry which is on the Verizon network...and that doesn't even render complete webpages like the iPhone.
Accessories
Other accessories? car chargers were available
Data / Sync
Can the iPhone data connection settings be modified so that it can be connected to other mobile service provider? not that I see
Does the iPhone work as a regular wireless modem (just like my current Nokia 6350 does)? i.e. can I connect to the iPhone via bluetooth and browse the web on my MBP? no
Music
Can you listen to music on speaker? Yes. If you don't plug in the headphones, it automatically plays through speaker.
Financial / Contract
Are you contractually obligated to features or a particular plan, or can they be changed whenever? what you see on Apple.com as far as rate plans are what you get
