Yes, that is correct. The K750i was released in June 2005, which mean we have provided update service for almost 8 years after the release. Same goes for W800i, which was released about a month after K750i.
@ Samuel Yes I agree.. However not completely convinced with the answer ! I still own a K750i and want to reinstall the firmware for the handset is not performing upto the mark. I visited service centre and they informed that handset is no longer supported and cannot be updated. Does it mean I have to throw away my K750i? To let you know I am not interested in flashing my phone for it might brick it ..
Since there haven't been any new firmware released for this phone since about 2008 you can perform a master reset with about the same results as a update in SEUS or PCC. Settings > General > Master reset.
