Please accept my apology. I have just found the cause of OAuth problem in 1.4.0 in OAuth library. And it is fixed.

Now even my dump phone, SE W810i runs jibjib javame 1.4.1 with OAuth flawlessly. I also test it on S40.

However, the authorize url must be opened on desktop browser. If you cannot type the long token correct, just click menu "Retry". I added this menu for this purpose. Retry until you can read all characters clearly without confusing.
