I assume you are talking about a Gevey sim, I have seen folks having issues after the custom firmware update to ios5 so I would recommend staying away for now, but as I said you will need to make a custom ios5 IPSW to restore to as you need to preserve your 4.10 baseband. If you want to know how then just let us know :)
