New t610

I bought my new t610 today (red) and have given up my nokia 7210 (which has
never had A bug on it) although I have read lots about them. Need 2 phones
so also have 7250i. When I transfer a business card from the 7250i to the
t610 sometimes the infrared works and sometimes it doesn't but it does not
copy over all the numbers for a particular person, nor the address. Am I
missing something here? Also does anyone no if there is a way to convert a
nokia ringing tone so that I can use it on the t610. I don't want to have
to get a cable so is there a way to download it via wap? Lastly I dont see
to have the lastest version in my phone. I have version R1A081 is that
going to cause me problems? Many thanks
