The Vodafone femtocell is nothing to do with UMA, however a lot of people cannot get it to work. My girlfriend uses an iPhone 3GS with her Vodafone “Sure Signal” femtocell and it works very well….

A friend of mine uses a Vodafone signal booster with his iphone 3G. Is that the same technology?

While UMA relies on specific hardware (most commonly an 802.11 radio), this hardware is already present in all iPhones. However, the iPhone currently uses the 802.11 radio only for data access.

In theory, that makes UMA a software issue on the iPhone hardware. To date, it appears that Apple has not implemented UMA. Perhaps it will come in a future release. Apple doesn’t have much reason to do so, as their carrier partner in the US (AT&T) doesn’t have UMA infrastructure. T-Mobile does in the US, to support their HotSpot@Home and associated T-Mobile@Home services, but apparently not in Germany, where they are the exclusive iPhone supplier.

Lmfao that’s not uma, that’s make it mine. It’s an app you can get from cydia if you have a jailbroken iPhone. You can get it to say anything u want in place of the carrier. Wow this noob went through all this trouble to fool us. Why? To serve what purpose? BTW UMA IS HARDWARE NOT SOFTWARE!!! That’s means no app can use uma since it’s not built in the iPhone. Since I already see that some posts go into great detail as to what uma is and how it works I’m not going to tire my thumbs. iPhone keyboard is annoying: ( but I do agree uma on iPhone is a great idea. Hope to see it soon.

UMA is a HARDWARE feature. if a phone doesn’t have it when it’s made, it will never have it.
UMA is NOT free calls.
UMA is very very simple. If a device has UMA and it can’t get a normal 800/900/1800Mhz signal from a cell tower but it is connected Via WiFi it will attempt to establish an IPSEC VPN connection to the carrier instead. If the VPN connects (routers and firewall permitting), then the phone just sends all it’s normal GSM, UMTS (calls, texts etc..) protocols over the VPN instead of by 900/1800Mhz radio.
THE CALLS ARE STILL BILLED AS NORMAL THEY ARE NOT FREE!!
The service is free to use though because it is good for the carier if you can use your device where you normally couldn’t.

I don’t think you are runnning UMA. When a UMA phone switches over, the GSM bars go away and they are replaced with another sort of strength meter. Some UMA phones show pink dots for the strength, and other don’t show the strength level other than a lower case or upper case UMA. The fact that it is still showing the GSM strength indicator means you are probably still on GSM.
