We had a similar issue at our office with Iphone 3GS and 4 not connecting to time capsule, but imacs,ipads, and macbooks having no problem.
Our fix: enable the guest login. We didn't want to do this because the network is no longer hidden, but it seems to work.
I was able to fix this problem by using an 8-character password for the wireless network, using WPA2 Personal as the security mode on my Linksys E3000 router. The router is OK with shorter passwords, but the iPhone requires at least 8.
Do exactly 8 characters and the problem goes away.
