I had a similar problem with my laptop. I send ringtones and pics to my 3200 via my laptops infrared with no problems. But my mums 7210i & my dads 6100 cant recieve anything. Anyone know why?
Im not sure about when transferring between 2 phones, but from my laptop to my 3200, my phone is usually 6 inches from the port, and not straight in line either.
6620 can send to the newer generation of Nokia phones, such as 6230, 3200, 6600, 7610 etc etc.. but NOT the olde generation, such as 7250, 6610, 6200 etc etc
The IR in the older s40 phones like 6200/7250/7210 etc is CRIPPLED.. meaning u can only send pics/tones to it via a computer and not via another device (pda, phone etc). The IR in newer s40 phones like 3200/6230 etc is NOT CRIPPLED and can send/receive pics/tones from other devices as well as a computer.
