As Nokia PC Connectivity SDK does not support Nokia 7650, it is not recommended to use it for development work with this phone model. At the moment there is no Nokia 7650 PC Suite for Windows XP, however there is Modem Setup for Nokia 7650 available also for Windows XP.
RE: PC suite for nokia 7650 compatibility whit windows XP
I suggest that we email via the common ISP to forewarn on the 7650 weakness (not working with XP) before more consumers got "trick"
into compatiblity issues with XP.
Restricting to Nokia forum will not help to make the public aware of of such deficiencies.
