Switched to WPA and transitioned the 8 other devices to WPA with the new password this AM and still get the Unable to join network "NETWORKNAME" warning. I have 2 new apple producets running the newest OS (an iPad 2 and an iPhone 3GS) that connected without an issue. Went on the Netgear Forum and one thing I have come to know about their product line is that they don't support anything that is end of life and they have a lot of wireless routers out there that are no longer supported. Anyway, their forums are full of examples of the same issue but I have also see it problem showing on D-Link as well.
I have also tried to remove the security protocol and changing the channel turning on and off the WMM(I think-this one is tricky, it is not listed on the administrative interface)
I don't want to have to try a factor reset on the phone unless advised.

Personally, I would reset the router to factory defaults before I would restore the phone as new.
I had the exact same model router that you are having issues with, mine simply failed after about 2 years, nothing would connect to it.

OK, I'm in and here is the fix for any of you that have a Netgear router of the WGT624v3 variety:
Open the router interface by opening a browser window and in the address bar enter http://192.168.1.1
Log in to the router -- User name = admin and Password = password (unless you have set it up differently)
On the left hand sidebar near the bottom Web Support and Knowledge Base
Near the center of the screen click on Get More Downloads then be sure the model number carried over, you may need to readjust that back to the WGT624v3 because it does matter.
Under Firmware/Software at the bottom of the list WGT624v3 Firmware Version 2.0.21_1.0.1 (North America)
(this is a 3 version downgrade in the firmware but it works)
Click the Download button in the pop-up then Continue without registration
The zip file will download and you will need to extract the file wgt624v3_2_0_21_1_0_1_na.chk file to a place you can find it later.
Go back into the router interface http://192.168.1.1 and log in as before if necessary
Under Mantenance click on Router Upgrade and then Locate and Select the Upgrade File from your Hard Drive: and then select the file in the folder you placed it. and then click on the Update button.
The router will take a few minutes to load and cycle but the iPhone will connect with any of the security protocols you are using in you other network devices,
I then made sure the modem did not ask me to check for updates so I don't screw it up again-- Yes, this is a downgrade of 3-4 versions and you would think newer is better but there is something about the new OSi that is not compatable, don't know if this is an Apple problem or a Netgear problem.
If you have a D-Link router, God help you but I'll bet there is a similar fix. Newer is not always better,
