A short review of the iphone from howardforums. 
Here's the short list:
1. Bluetooth is ONLY good for connecting a headset. That's
it.
2. There is no file browser on the device at all. Data must be
organized (if at all) in the appropriate application.
3. The camera is a simple application that has ONE button: the
shutter. Pictures come out okay on the device, but nothing too
fancy on a monitor, especially if it was an attempt at a macro
shot.
4. SIM card is damn near impossible to open, if at all. I didn't
look into it extensively.
5. Web browser is slow, even over WLAN. Even the simple OneList web
app that was created takes around 20 seconds to load over WLAN. You
can not highlight, cut, copy, or paste and text from a website, and
you can not save any images you find from a website either. The
only nice thing about it is the tabbed browsing, which crashed on
me when I went to Engadget and YouTube on two tabs. This is the
only application that allows you to use the keyboard in landscape
mode.
6. The keyboard sucks. It gets slightly better after the iPhone
"learns" you, as the employees said, but even then, it's not a
device you can use with one hand comfortably, much less without
looking.
7. You can only send one picture at a time in an email.
8. No custom ringtones (yet, as we were being told) and the alert
tones can not be changed whatsoever.
9. The default ringtones are incredibly lame.
10. The only form of customization outside of a lame default
ringtone is the wallpaper, which you'll only see when you need to
unlock the device or when you get a phone call.
11. "Picture pinching" or using two fingers to zoom on any content
is certainly fun to play with, but not practical whatsoever. This
operation depends solely on using the device with two hands.
12. No document editor or native viewer. You can not store
documents on the device to be viewed, they can only be viewed as
attachments when they're sent to your in an email.
13. Visual voicemail is laggy and reacts about the same way as
pushing the fast forward and rewind buttons on traditional
voicemail systems. The only advantage is for those that get that
many voicemail messages a day that they need to sort them according
to priority.
14. NO games. None.
15. No voice dialing.
16. No speed dialing (which can be made up by the "quick list", but
getting to that quick list isn't as fast as holding a single key on
a real keypad).
17. No video.
18. No MMS.
19. It's still
20. It only takes around 2 hours to explore every menu without any
options for expandability except to scrounge around for new web
apps that will load slowly and nowhere near as smoothly as the
native apps.
This device looks like it was aimed at the general consumer who has
the money to spend on such a flashy device, but it leaves so many
basic features behind that it's almost impossible to consider it a
success as a mainstream device. It encourages the advanced user to
move away from MMS and into email to send images, but leaves out
any advanced features advanced users would be accustomed to, and
still retains a huge price tag on top of it.
It's certainly pretty and Americans will buy it because of that
simple UI, but anyone who's familiar with other operating systems
would be appalled. This phone needs to be unlocked and cracked WIDE
open to make much better use of the multi-touch system. That, or it
needs an immediate update in iTunes to rework every feature.
