gps doesnt use the 3g/edge band signal. it uses satellite signal.

you have to toggle off DATA at BossPrefs.

and yeah, aGPS uses the help of data line initially to fix your location, but it doesn't necessarily have to. I've successfully used my gps with NO data countless numbers of times to get to places and it works just fine. Its just that it might take a while to get a satellite fix on your location if its cloudy..etc.

Check under more options, it might not be there by default but you might be abble to add it.

Btw why are you using bossprefs? that app is no longer maintained and its even stated in the disclaimer that you should be using SBSettings.

it will, cheers-

in SBSettings, go to more > Set toggles. Enable DATA toggle there

Is your iphone updated to new carrier settings? If it is not, you can go to your settings>general>network>cellular data network.

There, replace all the info for your current APN settings to meaningless inputs. "blablabla..ex.xsadsadewrasd?Q@#?"(username/pass..etc)

This will make the data connection fail, but if you do it this way you might need to redo this each time you restart your phone.

yeah, sometimes even when DATA is toggled off, it actually isn't.(especially after soft reboot/reboots).

one thing you can do is get the SBSettings toggle called Fake APN as well. extra guard your data blocking.

lol thats not how you do it.. what you have is just fake APN on while data is still running.(look at your data ip, it should be empty if data block is on)

you need to set the 3g, edge and data toggles on first so the buttons appear in SBSettings. Then IN SBSettings, switch 3g, 3dge and data OFF while Fake APN on.

your data isnt running because you have fake APN on. data toggle is a different thing, which is still left off but since fake APN is on, it does the job.

for extra protection, you should enable both toggles; then on fake APN and off Data

for the prepaid plan, as long as your line has validity for that month, you will get free 500mb data every month for the subsequent year upon purchasing the iphone.

this is how i'm using internet on my iphone currently, only thing is i have to switch sim cards each time i wish to do so as my main line is a normal postpaid package.

again and again im stressing, you cannot turn of EDGE. even if u use SBsettings or bossprefs to off it, you will notice the 'E' symbol still there from time to time.

also, even if u turn it off, your phone is going to use GPRS to get the data.

what you need to do is turn of DATA.(there is a toggle by this name)

yes, but at the cost of losing MMS function.

this works but there will be data leaking at times.

this is the best way. I did this last month, but sometimes I dont know how, the data just works by itself
