Sony Ericsson W810i -- Storing Contact Info in the SIM Card

First, please pardon me that I will be a new GSM user effective March 14, after LNP avails in Toronto. That's why I have no idea about GSM and the SIM cards.

I will be switching from Telus to Rogers and after much research, I am zeroing onto the Sony Ericsson W810i.

One of the reason that I will be making the switch from CDMA to GSM is the powerfulness of the SIM card (I thought) -- storing contact info inside that card and simply insert the card into a new phone when I switch to another new phone down the road (... hope this is not a myth!)

My question is: Since these new phones come with a USB cable that I can connect to my computer (and hopefully there is software [CD-ROM] coming with the phone), can I actually use my computer and the software to input contact info and then download them into the SIM card thru the USB cable into the phone?

I look forward to hearing from anyone of you. Thank you.

Nice phone. Very feature packed in a small bar phone. Best bang for the buck.

Nope, not a myth. Many GSM users do this. That's the flexibility of using GSM phones, switching from one device to another as the user sees fit. I do it.

Yes, a CD ( Sony Ericsson PC Suite) will be included in the package. However, if you ever lose the software CD, you can always download it from the SE website.

Thank you peryus88 for your kind reply.
