Aside from the fact that it's a cool piece of kit, I wanted to upgrade my phone and have one device for my music and phone. The iPhone is perfect because it allows me to sync my existing iTunes library whereas other phones would require me to set something up from scratch. Additionally, as mobile providers charge more and more for downloads the inclusion of an unlimited (but within reason) download limit was also attractive so that I don't have to pay through the roof to check my emails when I'm out and about.
Texting
I use my phone for texting more than anything so I was a little concerned that my chunky thumbs wouldn't be able to type properly on the touch screen keypad. Texting is far easier than I had feared. I was able to type quite quickly albeit in an error prone fashion. If you accept that it will correct your typos you can generally type quickly. When I was just using my (right) index finger I kept hitting b or v instead of the space bar. I have improved that since I started using my thumb to press the keypad and index finger for letters. I sometimes use my middle finger in a three-pronged attack. The Apple demo video shows someone using both thumbs in the same way that my friend types on her Blackberry but I'm not comfortably doing this with my chunky thumbs. I probably could if I gave it a chance but it doesn't feel right to me. I can also type old school, with one hand using just my thumb. I'm still having to go back and correct a few mistakes if I type quickly but the one real drawback of using a touchscreen to type is that one can't type without looking - because there's no keys to feel. [Since writing this a few months ago I've now taken on typing with both thumbs or just one thumb if i'm out and about]The SMS interface is different to all other phones I've seen. Rather than dividing texts into Inbox, Drafts, Outbox, Sent it displays messages per user as a continuous chat. This is good because it enables to look at the message you're replying to without closing a current composition. It also adds a feelgood factor by seeing a "chat" with a friend. However, the disadvantages are that, without an outbox, it's easy to miss that fact that you haven't sent a message (which I did on New Year's Eve and realised three days' later). Also, if you reply in quick succession to a message it only displays the time that the "conversation" started unless there's a reasonable amount of time between messages so you can't always be sure when you received/sent a particular message.
My other gripe with chat system texting is that you can't add a new recipient in the middle of a chat. If you receive a message and then want to reply with the same message to more than one person you have to start a new message and individually add each person. This is time consuming because you can't multi-select and add recipients.
MMS
iPhone current supports no MMS. If you receive one you get a text directing you to a website. However, the O2 website is not enhanced for mobiles so you have to zoom in - O2 should fix this. It seems likely that Apple will update the OS to incorporate MMS in the near future.
Emailing is good, using Gmail IMAP so that I have access to all my folders. Doesn't currently allow push (immediate) email unless you're on MS Exchange, yahoo or Mobile Me (a subscription service) but it's thought that push email will soon come for google mail. You can view attachments such as MS Word, MS Excel and Adobe Acrobat but there's no way of saving them.
Contacts
Contacts can be synced with Windows Contacts or Outlook but not Windows Live Mail contacts. I had hoped to sync with my google calendar but instead used Outlook and synced that with google.
Camera
Camera is 2MP but much quicker and therefore more effective than the 3.2MP autofocus on my Samsung U600. The quality is good enough for snapshots taken out and about but not of a high enough quality for serious photography. But, I always think you'd want a proper camera if you're going to get that serious about photos.
Web Browsing3G is pretty fast as long as you find yourself in an area with a 3G signal. However, web browsing is not that fast using the phone's in built Safari browser. Even on a WiFi connection is takes a while to load the pages. This is particularly noticeable when loading content heavy pages such as guardian.co.uk. No preferences can be set for the browser so there's no obvious way of clearing cookies and history. Without a 3G or Edge, web browsing is excruciatingly slow.
Battery Life
According to some reviewers and bloggers battery life has been improved in OS 2.2 but I can't compare it. Battery life is not long but it's to be expected considering the fact that it's essentially a small computer in your palm. Battery life is dependant on use and will last longer without 3G and WiFi. As it's still new and I've had some time off I've spent a lot of time using the phone which requires me to charge it every day but if I used it less frequently or "normally" I'm sure it would last longer.
iPod
I've only used the headphones which come in the box but the sound is an improvement on the Ipod photo I previously owned. There's greater depth of sound, even in traffic. It will also ring and play message alerts when listening to music, fading out and in accordingly. Alternatively, the phone can be set to silent/vibrate so that it won't disturb your playback.
Navigation is much quicker than on the old iPod but that should go without saying.
The iPhone and more recent models allow for gapless playback, eliminating the annoying half a second gap which would occur on live albums or Sgt Peppers.
General Use
There's not much of an instruction book and you need to watch the demo video on the Apple website to get the best use of it. The phone is easy to navigate with the touch screen which responds very well. It's only when using the slow web browser that it can be a little infuriating.
Applications
Applications can be downloaded directly to the phone over WiFi or 3G. It's extremely slow or impossible to download Apps on a slower connection but they can be downloaded via iTunes on your Mac/PC and installed. Some apps are pre-installed on the iPhone running 2.2 OS:
Maps has GPS and directions. Useful, but slower is you only have a 2G connection.
Podcasts can be downloaded over 3G provided that they're less than 10MB, otherwise it's WiFi only - just like purchases from the iTunes store. These purchases will transfer to your main library when you sync with your PC/Mac.
On a PC, at least, the syncing is quite slow. It's good that it creates a backup of the phone (and you can cancel this facility) but it seems to take much longer than it does an older models to update music. [Note, since writing this, syncing is much quicker following an OS upgrade]
I bought it from the O2 shop and Visual Voicemail was not set up by default. I had to check the o2 website to find out how to activate it. The server seemed to timeout when I initially tried to set up my password but worked after a while. I never get a great deal of voicemail but it's a really useful function - provided that the caller hasn't withheld their number.
No speed-dial by number but you can have a list of favourites and select from there - but this doesn't seem as speedy as opening the keypad and holding down a number (of course, that system requires that you memorise 8 numbers because you can't override 1 (voice mail) or 0(+ symbol).
Other info
BBC iPlayer can be watched over WiFi (only).
DVDs can be converted using software from the internet or you can by/rent from the iTunes store but only from a PC/Mac.
A lot of youtube is available but I don't think it's not as quick as when using a PC/Mac.
One can use the GPS to geo-tag photos.
Home key returns everything. Seems to allow only one application at a time. Don't seems to be able to navigate through different open apps. If you're using one App and you get a text, once done with that text you have to press the home key and then open the App again. It remembers your last position but it would be good and quicker (albeit more resource hungry) to flick between active apps.
Volume rocker on the side is convenient for pocket use, rather than unlocking an iPod and then turning the wheel.
Headphones come with a built-in speaker/remote. When listening to iPod one-click pauses and two-clicks skips tracks which is particularly handy if you're shuffling through 3000 songs. One click will also answer the one and it serves as the hands-free speaker. However, my clicker has now become a bit fussy about what it will and won't do.
Comes with a a few basic ringtones but it's simple to create your own for free. Apple UK isn't yet set up to create your own from the music that you've bought but there are videos on youtube which tell you how to get around this.
Alarm clock doesn't seem to wake up from sleep, like other phones do. If you don't want to be woken up by a call in the night you can switch to Airplane mode which turns off the phone function of the iPhone but sometimes you'd just like to turn it off overnight. A lot of people (me at least) use their mobile as their alarm clock.
Clock is set automatically (and accurately) unlike other phone which purport to do this but don't.
No crashing yet although I did have a couple of Apps which crashed but worked on re-install.
