The website you are referring to is in Bahasa Indonesia. It doesn't actually update your twitter status from a Nokia 3310, it just changes the "published via (your device here)". The other options are non branded chinese cellphones, borrowed cellphone, public telephone, etc. The programmer is from Indonesia, and half of devices is in Indonesian language (you can use Google Translate to ..uhm.. well.. translate it!). Actually, it quite funny if you have many Indonesian friend.. well geeky type of funny :-D
