I could backup 7650 data on my PC through the infrared device. I could send picture from my PC to 7650 and vice versa. I could dial-up to my ISP through the 7650 on my iPAQ (infrared also). I could also send pictures from my 7650 to iPAQ.... BUT my 7650 can't receive files such as .jpg or .gif files from my iPAQ. Anybody could help? Thx!
