Review of three iPhone docks

Different horses for different courses … all along I want to use my iPhone in three different places for totally distinct usages:

  1. Connect to a notebook computer, sync my iPhone but also house an USB hub and memory card reader;
  2. Connect to nothing, but iPhone as a loud music player in my small office;
  3. Connect to a mini-HiFi, my iPhone as the music and Internet radio source.

In other words, all I need is a multi-purposes devices – an iPhone dock that can connect to an AV amplifier but also a speaker, USB hub and a memory card reader. Of course, there is no such device and therefore I bought three docks to achieve this.

First is the Simplifi from Griffin Technology – It is a charge/sync dock, memory card reader, and USB hub. See the photos below for the look of it, it works perfectly and I am now using it with my notebook computer. It really is a space saver.

  • Pros : Hi-speed USB link, all-in-one device, not expensive, match with MacBook nicely
  • Cons : USB cable to connect to computer is not long enough

The second one is also from Griffin and it is a simple dock that also act like a mono-speaker – Griffin AirCurve Acoustic Amplifier for iPhone. The Aircurve, a cleverly-designed acoustic amplifier, is basically a coiled waveguide “horn’ that collects the sound from the built-in speaker of your iPhone and then amplifies it. Of course it is not a Bose speaker system, but it is good enough for my small office.

  • Pros : Stylish, not expensive
  • Cons : Not a small dock (check the pic), so-so quality loudspeaker (it is mono, after all), you also need to get your own iPhone cable to do the synchronization

Lastly, the Dexim AV Dock is similar to the Apple iPhone AV dock. It connects to my mini-HiFi and in turn to my LCD TV. Now with this AV dock, I can watch videos, view photos on my TV. And also I can play my iTunes music, Internet radio show thru the mini-HiFi.

  • Pros : An cheaper alternative to the Apple dock / cable, easy to set up, stylish
  • Cons : You need to turn the volume way up high to appreciate the music

Life is good.

Reading PDF documents in Kindle 2

Other than ebooks, lots of people want to read PDF documents in their Kindle 2 / Kindle 3. However, since the Kindle 2 cannot display PDF documents natively (Kindle DX can do that however), the big question to many Kindle 2 owners is therefore how to make it work ? One simple answer is to use the conversion service by, however this method is not the best one. I hope this blog post can provide a good answer to some of you.

1. Let do it for you

As mentioned, offers a service to let you just do that. You send your file to your Kindle email address and after a few minutes, Amazon will send the converted file (with .azw extension) to you (via Whispernet). It cost some money to do that, or if you want to do it free, send your PDF document to the free Kindle email address. With this approach you can also save the file and transfer to your Kindle 2 with the USB cable – i.e. it works prefectly if you’re outside US. The only trouble with this method is the converted file is actually not easy to read at all … if your PDF document is full of graphical images and illustrations.

2. Hack your Kindle 2 to do it

Yes, you can hack your Kindle 2 to convert PDF document automatically … just install the Savory tool by Jesse Vincent. This tool converts every page of the PDF document into images and you can read it in portrait or landscape modes.

I like Jesse’s implementation a lot, but I don’t want to hack my Kindle 2 … and I don’t like to uninstall the hack before every software upgrade.

3. Convert to Mobi file format

Kindle 2 supports many formats such as .Mobi, .prc and .txt format, so you can also install file conversion programs to convert your PDF document to .Mobi files. I tried this before with the Calibre opensource tool. And there is another tool from that can do this as well. Unfortunately, the converted PDF document looks pretty much like the .azw format – i.e. not that readable for image-heavy PDF documents.

4. Convert to images without hacking your Kindle 2

That method is similar to the second approach above, but you don’t need to hack your Kindle 2. Just download the PDFRead 1.8.2 from the website, install it and convert your document with the profile parameters (check image below). Transfer the converted document (a .prc document) to your Kindle and it’s done. The upside of this approach is the very readable output (including Chinese document as well !!). The downside is you cannot perform text search with this image-based document, and many times you need to zoom in to read the details.

Check the images below …  hope you find this useful and enjoy your PDF documents.

Update 1: Amazon announced a firmware update to support native PDF reading in Kindle 2. Check my blog post for the step by step upgrade procedure.

Update 2: Amazon also announced Kindle firmware 2.5 to cover PDF Pan and Zoom.

Update 3: Get your Kindle 3 to have all the PDF functions.

Update Kindle software outside US

If you know how to download Kindle books to your Kindle, then it is not difficult to update the Kindle software at all especially you can find the detail instructions in website (after sign into Amazon, select Kindle > Kindle Support > Kindle Software Update).

I upgraded mine but I found that there are one or two steps not the same as in the Amazon page, so here is my version of the steps (some important steps are boldfaced):

  1. First verify your current version with this steps – From your Kindle, click Home Key, Menu Key, select “Settings”, check the version in the bottom status bar. In my case it reads Version: Kindle 2.0 (29133xxxx).
  2. Since we are outside the wireless service area and therefore cannot receive the software update wirelessly, we need to download the latest software to our computer and transfer it to our Kindle via USB.
  3. Before the download, you have to check whether the latest version (2.0.3 as of May 2009) is available to you – as Amazon rolls out the software update to the Kindle users batch by batch. You can check that also from the Software Update page, scroll down and you shall see what software version is available for you to download. If it shows 2.0.2, then it’s not the latest version.
  4. Then in the same page, download the latest software – make sure you pick the Kindle (2nd generation) and the latest version is 2.0.3 (i.e. this is available to your device to upgrade).
  5. Follow the steps as in the Kindle software update page to connect the Kindle, transfer to Kindle, disconnect Kindle etc.
  6. With your Kindle, press the Home Key and then Menu Key, then select “Settings” from the Home menu.
  7. From Settings screen, press Menu Key again, select “Update Your Kindle”. Please note that this menu option will be grayed out if the most recent update has already been installed.
  8. Select “Ok” when prompted if you want to perform an update.
  9. Next you will see system message and progress bar to report the update status. The Kindle will also reboot itself to bring back to the home page.

That is it. Press Home Key, Menu Key and “Settings”, you shall see the latest Kindle version in the status bar … in my case. Version: Kindle 2.0.3 (32761xxxx).
