I'm sure this has already been asked, but I couldn't find it with a quick search: Is there a reason there are no WiFi Signal Strength Apps (unless you jailbreak)? I'd like to measure the WiFi signal in my house, with more information than just the three bars. I use inSSIDer on my PC to get detailed information. An app for the iPad would be very convenient and a great utility. If there's one available, please let me know.
