    I was just wondering if there is a way to check WiFi signal strength? No not just the strength out of the 3 bars :p, but similar to that of checking cellular strength (-87 for example etc.) in Field Test Mode.

    How about this? Not quite what you're looking for, but seems better than relying on the default wifi icon!

    iTunes is giving me the "iTunes Store is not available" right now error. Could you give me the name of the app so I can search it up manually?

    Thanks for the suggestion.

    It links to WiFinder. From the developer's page...

    The screenshot shows that it displays signal strength as a number for each WiFi source found.

    EDIT: Darn, it's a paid app. I'm not really willing to pay for that. So I guess no free alternatives?

    From the Phone Keypad type: *3001#12345#* and then press the "Call" button

    This will show signal strength in dB.

    On average, mine shows the following:

    1-2 bars = -103 to -99
    3-5 bars = -93 to -77

    Seems fairly consistent anywhere I go.

    Ah cr@p.....stupid me....Wasn't paying attention....I'll go back to sleep....

    WiFi signal strength is what he's looking for, not cellular signal strength.

    That is a very powerful app, you do realize applications take time to develop. And an application that does what WiFinder does probably took at least 50 hours. Considering professional developers make at least $50/hr, that App should net him about $2500 in the long run.

    I do realize, it's just at the moment I'm not allowed to download $ apps, which is why I was asking for a free alternative.

    Then why did you said "I'm not really willing to pay for that"?

    I stand corrected, I mis-worded my response. At this moment I can't buy paid apps.

    The app either is not compatible with iOS4 or it's junk, as it just freezes up at "Updating" upon every launch.

    It's very hard to believe that there is not a good WiFi sniffer app for iPhone, but my searches continue to come up empty. Perhaps this is a market for you developers? :confused:

    I can't believe that there are no apps for measuring WiFi Strength on iPad or iPhone. Some rooms in my house have bad Wifi reception, and I need an accurate measuring device to try to improve it.

    I just downloaded Netstumbler to use on my Laptop to to measure WiFi strength. I will see how it works tonight.

    inSSIDer is a great free program that I use on my 64-bit Windows 7 laptops. From their web site: "Our award-winning, open-source Wi-Fi scanner software, inSSIDer, is an alternative to network scanners like NetStumbler. One big difference: inSSIDer actually works with Windows Vista, Windows 7, and 64-bit PCs."

    I have a previously jailbroken ipod touch. I restored my iphone data from it. It had numeric wifi. Now my phone does, as well as numeric battery.
