Help Firmware upgrade after rooting

Hey all,

I just bought the S 2 and had to root it too make it able to connect to Ad-Hoc networks, and now Kies is saying that there's a firmware upgrade available.

My question is: If I upgrade the firmware, will I lose the root access and the modification to make it able to connect to Ad-Hoc networks (it's a modified wpa_supplicant file) ?
