jibjib has been in beta for many months. That is because it is not stable yet. I added so many features and now it is very clutter. The degree of usability dropped a bit and I have heard many feedback about incompatibility issues on some phones or some brands. The way to go is J2ME Polish. I have prepared the code for Polish for a while but no chance to try it yet. Last week, @bact helped me experiment and gave me a patch. As a result, the latest beta and so on of #jibjib will support specific phone devices.
Many people told me jibjib taking picture slower than PlayGround. In fact, the problem is thumbnail function. J2ME does not have native image resize function so I have to implement it myself. I do not understand graphics stuff much so I just copied from somewhere on Internet and the result is this slowness. Today I find another function that runs faster than ever. The optimized code was written by Kamanashis Roy.
Kudos Kamanashis Roy!
Today, December 1, 2008, you may notice something weird in jibjib. It is my fault. There is a serious bug that leads to incorrect date/time parsing. All tweets will show as 335 days ago. I have just fixed it in this early morning after I saw on the road. In addition, I extended maximum length of each update to 160 characters to cover all retweets which also include "rt @screenname".
I strongly recommend to upgrade immediately for the best experience.
