I just got a new, faster modem from the cable company. In the process everything I have connects to wifi except the 3gs. I have my lap top, an iphone 4gs and an Ipod touch, which is older than my 3gs and all connect fine with the exception of the 3gs. I have called the cable company and apple support and no one has an answer as to why the 3gs won't connect. I have tried everything and it is very frustrating. Any comments or solutions are appreciated.
