this is really important for me to switch between Wifi & 3G on iphone via code .
so is there any possibility any backdoor or some way to crack. i can scan all the wifi hot spot and can drag their details but i need a background process that help me to scan 3g also and allow me to auto-switch whenever it finds wifi
You dont need to do this in code.
The iPhone does this automatically for you anyway. As long as you have a wifi enabled on the iphone, it will pick up the wigi signal and when it can connect will automatically switch to the wifi signal.
Hope this helps.
Let me know if it did a little. thanks

I'm working on test automation for an app. I'm looking for a way to automate connectivity tests. For that I need to be able to toggle 3G and wifi. I've been going through the private api headers but I haven't found a method that would scream 'I do that!'.
Can anyone point me in the right direction, please?
I can't see this being possible. The iPhone 4 has a setting for 3g on or off in iOS 5, but the iPhone 4s doesn't. If it was possible to turn off 3g in the iPhone 4s I think Apple would have retained that ability in iOS 5.
I assume you've seen the reachability sample code
Thinking about this laterally, iOS connects to known WiFi hotspots when available - so you don't necessarily have to run this on the phone. You could just toggle your WiFi hotspot which you're connecting to on/off, and iOS should automatically switch (as long as any other known WiFi access points aren't in range) to 3G and WiFi respectively.
I am testing the Reachability api, but my physical device only has WiFi access, as I don't have a phone contract. My code needs to distinguish between being connected to 3G/2G or WiFi. Is it possible to simulate a 3G connection on the iPhone simulator?
Clarifications: I am using Snow Leopard. Limiting the bandwidth is not what I need. I need for the actual interface to be identified as the 3G or 2G radio, as opposed to WiFi.
If you are using Lion try the Network Link Conditioner
Nowdays there is a part in Preferences on the device (when registered as a developer device) where a "Network Link Conditioner" is available.
You might also like Speed Limit.
Edit: I'm not sure if this will work as an identifier for 3g though. I'll update my answer after I do some tests (I'm working on exactly the same thing right now!)
I dont think that it is a build-in-functionality in iphone-simulator. But I test it sometimes on my device with wifi (and 3g) disabled.
If you dont have an iPhone but sth. similar (Android for instance) then just enable tethering on your device and use the tethered internet-connection. Then your iPhone-Simulator only gets slow speed ;)
edit: another idea is to limit the bandwidth of your mac. I found this tool online (have not tested it) which should be able to limit network-traffic (to your local router/modem)
I'm curious if it's possible to have more than two iPads/iPhones connected to one another over a bluetooth network simultaneously. I'd like to design a network game that supports more than two players but I can't find any information to determine if this is even possible.
Bluetooth only supports Device-to-Device not AdHoc. As "pst" suggests, WiFi is the only way to go.
if... you want to try.... first they would have to be jailbroken.
on cydia, try out the wywi app >> bluetooth tether with the pc
it has other functions like usb tethering, its the best tethering app if you dont care about revealing your connection to your carrier, but that doesnt suit the case
i know for a fact that you can tether as ad hoc via usb tethering, i believe the bt tethering should work the same
Can somebody explain why the reachability app behaves strangely?
I built it under IOS 4.2
When I start it, all three text boxes show an available network.
If I turn the airport off, they all show no connection.
Turning the Airport back on again only Remote Host and TCP/IP routing are shown as availabl. Local Wifi remains 'Access not available'
This may seem like a dumb question, but did you build it in the simulator? Results on the simulator won't mirror those on the device, as the 3G in the simulator is simply an abstraction of the wifi radio in your Mac. You'll need to use a device in order to see it work.
does anyone know if there is a way for an iPhone app to continuously detect the presence of WiFi networks while running in the background? What are the limitations?

you can see all the details(all SSID, RSSI) of nearby WIFI hotspots but i dont know how to inject this code so that i can run on BG
