  • Can anyone help me get the field test mode code for my Iphone 4.2.6 I need it to help set up my Wilson DB PRO repeater 

  • OR You can use the Spotlight Search by typing "FieldTest"

    Also try "iOS Diagnostics"

    XD

  • @jprincesa85 That's this? ---> 

    Is it an iPhone emoticon? If so, how did you post your comment to youtube? For some reason when I post comments on youtube from my phone they don't show up, and I've tried a few youtube apps thus far.

  • @Chunderitis Many of mine are too. I think it's because my phone is unlocked and jailbroken.

  • @lilweezyana323 That's his Signal Steanght Bars represented as numbers.

    I don't know how the numbers work though, as I set my phone this way once and it said -80 or something and at the time I had great reception, so I don't use that feature. The Wi-Fi and 3G can also be set to numbers, but I find it all confusing and stick with the visual icons instead.

  • whats that -75 on the top left of the phone?

  • All my values are unknown....

  • hi gjtfreack, The field test is an app that gives you parameters like the received power of the cellular radio base stations. If you have an Iphone 3G you should check in the UMTS menu, so you can find all the parameters of the station in which your cell phone is attached to.

  • ....1 question is this app depend on carrier ??

    on my rr info menu is all unknown ,,......

  • on 3.0 u can just search field and it comes up
