Finally it back to working condition.
But i found out whenever i tried to install something in Cydia.
It turned to be very laggy, especially those app that needed to be reboot.
Hardware problem?

laggy?? neh..h.w mebbe...f.w. prb mebbe but at least up and running mer

Yalor...
But i am on 2.0.1,Luckily dint go to 2.0.2?
Hahaha...
Another problem, when i connect to my office WIFI,
I can only go to safari.
But all other applications(let say Cydia, Weather, Map), cant be used.
When i was in FW 1.1.4, it worked perfectly.
FYI, my office WIFI is connected thru a gateway, which i already configure the acces.
But still kenot use other app other than Safari.
