Hi
I got Nokia 7600 (3 network in Aus) with v03.05 . My phone can read 2g sims like VF and Optus. If I wish to update it to v4.03 or 4.05, will my phone loose the ability to read 2g sims.
If No, then what could be advantages of updating and how can I do it myself if I have the USB data cable with me.
I am sorry for such a newbie but I am very new to such stuff. I will appreciate patience and help from all of you.
Cheers!
Aqif
