Sa-Weet, it finally is here (Internet Sharing). I have'nt tried it out yet but I got the upgrade a few nights ago. Like most people that I see replied to this thread they say that their MAC address changed. I have MAC address filtering on my router at home and after I did the update I noticed I also could not connect to my wireless network. Is there an easy way (on the phone) to see what your MAC address is? I had to turn off my MAC address filtering and connect. My router has a search function to see what connected recently and gives the MAC address, from that point I can just re-enable my MAC address filtering and input the new MAC address. I had heard one user saying that you get a new MAC address after each and avery restart of your phone......any truth behind that?
