When you're out and about, you might need to access your website or simply check something on the Internet. If you know where the closest Wi-Fi access point is you can stay online more effectively. These are the Wi-Fi detection apps that I found for the iPhone listed by price.
Auto WiFi Lite
Auto Wifi Lite is the free version of Auto Wifi. It stores your access information so you don't need to open a Web browser to get into your Wi-Fi networks. The lite version forgets your stored settings every 4th time you access them. You need to pay for the full version to have it remember them forever.
This app is free.

Easy Wi-Fi keeps track of the access points you use and logs you into them automatically. It supports many paid networks and will add any that you use that aren't in it.
