I had a 1.1.1 OTB iphone and WIFI allways go OK. Then upgrade to 1.1.2 and my WIFI problems started.

WIFI log in my router but I can't see web pages. Is a DNS problem because when change DNS to open DNS 208.67.222.222 and 208.67.220.200 I see web pages correctly. The DHCP in my Iphone dont work correctly!.

Upgrade to 1.1.3 and the problem still.
In some router (free or secure) I can navigate and in others no, weird!.

Some idea?

I have had similar problems , just remember those IP addresses and add them to all of your known WIFI settings. Do you have these DNS sever addresses in your router or is your router taking its DNS from your ISP ?

I solve momentarily setting static IP for my ruter.
The problem is in other (public) routers. My iphone can't catch correct IP and dns settings.
I try several times reset all network settings and nothing.

This is also happening to me since I upgraded to 1.1.3 (ZiPhone Mac). Never had this issue before on 1.1.1/1.1.2. Must be something to do with ZiPhone jailbreak?
