[Chinese]HTTPS Authenticaiton failed on Windows Mobile phone when access Facebook mobile site

最近看了商週成功者的筆記本專欄,文中觀念提到3分鐘作筆記的時間可以節省以後3小時找不到資訊的時間浪費,覺得甚有同感,也開始把以前處理問題的一些經驗寫下來作為自己的參考,當然也希望看到這篇文章的你/妳可以節省一些搜尋找答案的時間
這個問題是一家國際WM手機大廠工程師field test實際場測後反應給我們的問題,確時時間點我有點忘了,依稀記得可能是2009年下半年吧發現的問題是使用Windows Mobile(註:當時的版本是WM 6.5)手機使用HTTPS協定(via WAP gateway)存取Facebook Mobile Site會失敗但是換成HTTP就沒問題,原本以為只有該廠商手機有問題使用手上有的另外一個WM手機大廠手機發現也會有同樣的問題,查了一段時間以後發現錯誤原因是Facebook網站使用的root certificate沒有預設安裝到Windows Mobile手機上所造成,筆者發現Microsoft MSDN網站在2007年11月已經有一篇文章談到這個問題,筆者節錄該網站上的原文如下:
Facebook authentication uses HTTPS communication for security; however, on Windows Mobile this causes a problem because the root certificate used by Facebook is not provisioned on the device by default. This means that secure HTTPS requests will fail. Luckily it is possible to work around this by downloading the root certificate and adding it to the device.
Information about the list of root certificates can be found at http://www.geotrust.com/resources/root_certificates/index.asp. This can seem rather daunting as the list is particularly long; you need to find the entry called “Root 5 - Equifax Secure Global eBusiness CA-1.” There you’ll find download links to save the .CER file. The certificate is available as both DER encoded and Base-64 encoded; if you are using Windows Mobile 5.0 make sure you pick the DER encoded version of this file. For Windows Mobile 6 you can use either version. https://www.geotrust.com/resources/root_certificates/certificates/Equifax_Secure_Global_eBusiness_CA-1_DER.cer
有興趣FB開發的讀者可以跳轉到MSDN的這篇文章,原文連接在此 http://msdn.microsoft.com/en-us/library/bb932386.aspx,前述問題的答案在Root Certificates這一段章節解決的方法也很簡單就是依照不同的Windows Mobile版本下載不同的Root Certificates安裝到手機上即可
當時筆者給該廠商的建議是把這root certificate預設安裝到他們的Windows Mobile手機上,該廠商HQ的PM決定如何我不得而知,不過往後倒是沒聽說有再反應類似的問題就是了
至於其它品牌的Windows Mobile手機因為我手上的設備也不多,所以就沒有測試了如果你/妳正好是CPE設備商,不巧也碰到這個問題希望這篇文章對你/妳有幫助

[Chinese]-[介紹] Skyfire 手機瀏覽器

之前看過很多篇文章在討論Skyfire browser,今天AAS又出了一篇文章討論它.  呵呵,選日不如撞日,今天就來給他試試看吧!

安裝完試用了幾分鐘,感覺是個很有潛力的產品,它可以提供您類似於PC的使用經驗. 如果您用的手機是智慧型手機例如Symbian或是Windows Mobile,建議大家都去安裝使用.  等這個軟體開發完成,應該是可以取代您目前手機上笨笨的瀏覽器.
行動網(Walled Garden Mobile Portal),應該是岌岌可危了.

您可以使用手機上的瀏覽器拜訪這個網址 http://get.skyfire.com,它的程式會自動判別手機型號,您確定後按下載按鈕即可.

AAS網站上有發表過好幾篇文章介紹這個瀏覽器,最近一篇文章(9th Dec, 2008)是由Steven Litchfield發表的,您有興趣的話可以點擊這點.

AAS上的文章一向不錯,所以在此我就不班門弄斧了. :) 就貼一些螢幕截圖給大家參考看看.

程式開啟畫面,告知您仍然是測試版.

瀏覽器的預設首頁.
您注意到了嗎? 是不是看起來跟一般PC上的Portal首頁一樣,這就是厲害的地方啦,它可以提供您類似於PC上的瀏覽使用經驗,這軟體應該是我印象中目前為止最接近的.

您可以看看每天新聞頭條.

其他語言版本的Portal畫面也沒問題,秀一下我常上的中文新聞網站.
當然您的手機上面要安裝有亞洲語言(例如中文)等字型才能正確顯示啦.

看看NGN LIVE Web 2.0 Portal,一樣是沒問題啦. :)

還可以zoom in一下,注意看......文章.

可以看影片嗎! 來試試YouTube吧!

有圖有真相.
影片可以直接在瀏覽器裡面播放,不用跳到外掛程式去了,感覺起來還蠻順的,不知道他們怎麼做到的.


其他一些關於使用軟體上的T&C以及軟體支援的手機型號等問題,可以在 http://www.skyfire.com/about/beta 此獲得解答.

試用後您會愛上它!

Mobile VoIP and IM : Fring


The next thing I am going to discuss is VoIP. Apparently there are lots of options available to you. Skype is very popular. Unfortunately it’s mainly to be used on your PC. On your mobile phone, I recommend to use Fring. One single client can connect to Skype, MSN, Yahoo, AOL and even SIP. You can chat with your friends no matter what kind of IM they use. And the best part is, you can even buy a dial in number for either your Skype and or SIP account, then the Fring software can be used as a 2-way communication tool.
I have found that its voice call quality is very good most of time providing both parties in call conversation are not traveling in high speed both under 3G mobile network's coverage.

Features highlight of the Fring software are
  • A mobile client to do IM and VoIP
  • Support Skype, MSN, Yahoo, AOL and SIP
  • Can do traditional pstn/mobile call out via either Skype or SIP
  • Native client is compatible to Nokia Symbian, Window Mobiles
  • Fring Lite (Java client) was introduced recently to support mass market feature phones
This is the second software I will recommend you to be on your mobile device.
