Cannot Authorize Phone

Oke, the first annoyance about the Nokia E61 is a fact. Well, actually it's about the Nokia PC Suite with which you can connect the phone to your (Windows) PC. Somehow my Nokia E61i wouldn't connect using bluetooth with the Nokia Software. It could connect to the PC itself, but the Nokia software didn't want to 'see' the phone. So I tried to remove the pairing between de two devices (which seemed to work). After that I tried to pair the two devices again... That's were the trouble started. The software did see the phone via bluetooth, but it gave an error when I wanted to connect. The error said 'Cannot Authorize Phone'. Connecting via the USB cable worked fine. I tried rebooting the PC and the phone several times, but the error persisted. Finally I removed the software from the PC and reinstalled it. Same error occured :mad: . This was the point when I seriously thought about going back to a Windows Mobile device. There was one more thing I might try, and that was going through the registry of the PC and remove EVERY reference to Nokia. I first uninstalled the software and afterwards I removed everything Nokia-related in the registry. After a reboot I reinstalled the Nokia PC Suite software, and everything worked fine. This proves that Nokia software is as buggy as Microsoft software. How hard is it for a piece of software/developer to remove all references to the software when you remove it? (rhetorical question)

Installation Root CA on Nokia E61 Made Easier

From this day on, you can install certificates from non-trusted CA's on your Symbian-based phone (like the Nokia E61) using this page euh.. this page.

UPDATE: it seems that most other phone brands and types work as well (the S40 based devices are left out... sorry).

All you need to do is make sure that the certificate is in the DER format. The webpage doesn't verify if the certificate is in the correct format. This is up to the uploader.

I created this page, because I work a lot with digital certificates, so I don't want to be bothered with the workaround described in the earlier post. The current version is quick-and-dirty (no error messages). I'll try to make it more user friendly in the next couple of days (like having the option of sending the URL to an e-mail address). Just make sure that you obey the guidelines shown on the page, and all should go well.

Feel free to add a comment on how to improve this.

Import Root CA in the Nokia E61

Last week, I recieved my new Nokia E61i. As soon as I tried to connect to my own IMAP server (over SSL/TLS) is started nagging about the (selfsigned) SSL certificate.

The E61 has a certificate store, so I should be able to add other Root CA's to this store, but this is where the trouble began.

The manual has a chapter on certificates, but it lacks a working explanation on "how to import third party root CA's". On my old iPaq, it was simply upload a DER encoded certificate, click on it, and it would install. Well this doesn't work on the E61 (and many other Symbian-based) phones. Just 'google', and you'll find lot's of people with similar problems...

The working solution I found uses a website from which you download the certificate with the phone, but there is a catch; you need to add a MIME-type to the website containing the certificate (hence the admin rights).

Multiregion Pioneer DVR-545H

My latest DVD Harddisk recorder is a Pioneer DVR-545H. Since these things are still region locked I needed to do some searching on how to get the thing region free. In my early DVD years (when a simple DVD player costed about 700 euro), I bought lots of DVD's from Amazon in the USA. The reason for buying them at Amazon was that the prices were much lower, and they had a bigger collection to choose from. Every DVD player I bought afterwards had the possibility of making it region free. Mostly by a hardware modification, or with a hacked firmware. My latest acquisition had the possibility to make it region free by sending an infrared (IR) signal to the player/recorder All you need is a PC/Laptop with an IR out. On this page, you can get a 'kit' which makes your DVR-545H region free without hacking the firmware or making hardware modifications. Just one click on your laptop, and your Pioneer DVR reboots, and is region free. Note that the page is about another DVR from Pioneer. The nice part is that Pioneer standardizes their recorders, so it works on most of them. So again, no need to 'backup' my DVD collection to remove the region coding. And before I forget to mention it.... Use it at your own risk!!.
