Nice read though!!

You just need to unlock one and it’ll accept sim cards from whatever network in whatever area/region you’ll find yourself and it’s perfectly legal(something in to do with a ToS clause that goes ‘ownership and responsibility is fully transferred to your hands upon purchase’) .It can be done remotely via the modem make and IMEI.

I guess that in a perfect world with unlocked iPhones, the iPhone’s internal field test mode (*3001#12345#*) would also show the signal strength of other networks (“mobile network code” = same for all listed base stations). But because an iPhone is usually designed to run on one network only, I’d assume that it only lists other, neighbouring base stations from the same network (with all their details though, which might still help in order to move the phone to a better position). So, even if there are iStumbler-alike apps around for the iPhone, you’d probably only get them via the extra repositories/rock/cydia where Apple’s strict policies do not apply.

I am still to find the S60 app that brings back field test mode to modern Nokia phones (it is somewhere out there). Field test mode used to be included with most older Nokia phones where it also listed the signal strength of other networks. However, those were GSM-only phones.

There are some RF-metering apps available for Android (and imo most likely that we will see more dev. here), e.g. http://www.gadgetsdna.com/how-to-check-signal-strength-of-android-phone/1120/

Another alternative I can think of is the Windows-only tool MWconn (http://mwconn.net), which provides connectivity to a mobile network (instead of using the software that came with your umts modem) and also has a test mode where it will list other available networks and their RX/TX ratio. Linux + Mac = sijui, pole!

Else… even with a dedicated device that will spot network coverage and display signal strength for different networks at the same time, I would still only trust my own modem because the signal detector gadget and the GSM/UMTS modem may still have two different antennas layouts and positions, so what applies to the detector may not necessarily apply to the modem. Hence the (interim) software solution via the computer.

my phone can tell me if it’s picking up a SafariCom signal, when I have my SFCM SIM in, or Zain, when my Zain SIM is in, but it would be nice to have a small device that can pick up any cell signal and who the transmitor is. That would be handy. (PS. my iPhone actually does this, but doesn’t display the kind of signal, just the carriers)

Glad to know you’re still using that netbook, Erik! Even though I think we shd update to a 11,6″ version one day
