Try Resetting Network Settings on the iPhone, go to Settings> General> Reset> Reset Network Settings, Reset Network Settings.
If the issue persists after Resetting Network Settings you may want to take a look at the router configuration.
Have you tried to power cycle the router?
Is the router setup to distribute enough IP's for all the devices on the Network?
Does it have MAC address filtering? If so make sure the iPhones Wi-Fi Address from Settings> General> About is added to the list.
You can also try to restore the iPhone to rule out software issues with the iPhone.
Power cycling the router may have done the trick. After a few days my girlfriend's iPhone connected fine, for no apparent reason. The router had been switched off and on a couple of times over the days though. I'm still not sure what caused or what fixed the problem. The router is configured to let any device connect as long as the password's correct (which I'm absolutely sure it was), the phone connected to other networks fine, and my Macbook and my own iPhone had no problem at all connecting to my router.
In the mean time however, I had my own iPhone replaced (because of an unrelated issue). I got the replacement today, upgraded to firmware (2.2) restored all my stuff from a backup, and now find it won't connect to my home network. Same issue as above.
I've Googled around, and have found many reports of the same problem, but no one seems to have a definite fix. I'm just hoping for the issue to go away spontaniously like it did the first time. Any suggestions much appreciated.
