cellular-network

I have a toggle in my app that's "download on WiFi only". However, that toggle is useless for iPod touch or WiFi-iPads. Is there a way to know if the device has cellular data capabilities in code? Something that would work in the future would be great too (like if an iPod touch 5th gen with 3G comes out). bentech Hi you should be able to check if it has the pdp_ip0 interface #import <ifaddrs.h> - (bool) hasCellular { struct ifaddrs * addrs; const struct ifaddrs * cursor; bool found = false; if (getifaddrs(&addrs) == 0) { cursor = addrs; while (cursor != NULL) { NSString *name = [NSString

Just wanted to know whether it's possible to get cell tower changes in Android? I have seen an event called onCellLocationChanged in PhoneStateListener . Can I use this to detect cell tower changes ? This is the correct method. It is always called if you are in a new cell. See the documentation here: http://developer.android.com/reference/android/telephony/PhoneStateListener.html#onCellLocationChanged(android.telephony.CellLocation ) Glenn This is not true. onCellLocationChanges from PhoneStateListener is ONLY called when the phone is NOT sleeping. You have to wake up the phone (force a

Is there any way to identify if iPhone supports CDMA or GSM network. Any Apple API in Objective-C which can provide this information. You might examine model id with the function ( credits ): #include <sys/types.h> #include <sys/sysctl.h> NSString* machine () { size_t size; // Set 'oldp' parameter to NULL to get the size of the data // returned so we can allocate appropriate amount of space sysctlbyname("hw.machine", NULL, &size, NULL, 0); // Allocate the space to store name char *name = malloc(size); // Get the platform name sysctlbyname("hw.machine", name, &size, NULL, 0); // Place name into

I am working on an iOS app, and want to determine which type of cellular connection the device has. I'm most interested in the kind of cellular network my device is using: 2G or 3G, or other. However, the Reachability.h only provides checking for wifi or 3G. How can I check for 2G, 3G, etc? 2G / 3G cannot be distinguished via Reachability.h or any other third party libraries, as iPhone only provides network type information ( WWAN , WiFi , no Network ) to API. However, if you are able to know the IP range of 2G or 3G network, you can determine which network speed / frequency the iPhone is
