    At home I am using WEP and my wifi constantly drops from wifi to 3G on and off. I never had this problem on my older iPhone before. But when I go to my friends house, or the Apple store where they use WPA, it connects great. I was just wondering if this is normal for the phone or should I get a replacement?

    I'm hesitant to get a replacement though because I don't seem to be having an issue with the lower left hand corner and reception. I've grip that thing as hard as possible for a few minutes and haven't lost a bar. Thoughts?

    Well, if WPA wireless networks don't seem to be an issue, why not change your WiFi at home to WPA? WEP is hopelessly broken, has been for years. Someone that knows what they're doing can break WEP in a matter of minutes and sniff all of your "secured" WiFi traffic: http://hardware.slashdot.org/article.pl?sid=07/04/03/2116239

    I just have so many devices on the network already, it seems silly just to change it for one device. But you do have a good point about WEP being broken. I just wanted to make sure my Wifi isn't broken, or why it's not working on WEP. Damn you OCD! haha.

    Not sure if it's related but I had a similar situation of wifi to 3G unexpectedly.

    I've got a time capsule set to N only, had it on N only, 5GHz. Have a separate airport express on B/G only so they don't slow down my N network.

    Had my 3GS on the express B/G with out problems. Got the iPhone 4, but decided to keep it on the B/G network so it wouldn't drag my N network down. When I upgraded my partner got my 3GS and joined us iPhone users, also on the B/G network.

    After this the wifi started dropping for our phones and switching us to 3G. Just changed my time capsule to N only, 2.4GHz and switched my iPhone 4 to the N network. So far so good.

    I really don't see why this should fix it, but I have to try to see if this is it. I will let you know, hopefully it does but time will tell. Sorry if this is nothing like your setup but hopefully it helps? Btw I'm on WPA2, I would also recommend changing to WPA over WEP for security reasons.

    I have an original iPhone and my girlfriend has a 3G. We tested it out earlier and the other two iphones kept a signal, but the 4 didn't. But when I tried at her house and the Apple store which are WPA I don't drop off the wifi at all.

    That's just all the more devices on your network that are communicating over a insecure and outdated encryption method. Just look at the damning evidence in the Wikipedia article on WEP: http://en.wikipedia.org/wiki/Wired_Equivalent_Privacy

    IEEE deprecated WEP all the way back in 2004. It's time to update your wireless network for the sake of your own security first, and secondly to hopefully get your iPhone 4 working ;)

    No prob. Please let us know if changing your wireless to WPA fixes your iPhone 4 Wifi woes, it would be helpful to others who stumble on this thread that may have the same issue as you.

    I'm going to change everything in the morning. I still hope there is a fix with WEP so I can use it at other people's houses, etc. after I change mine to WPA.
