Given that one of my two main reasons for potentially leaving Orange is the poor indoor reception in one of the locations I use the phone, I'm intrigued by this. However I understand that UMA is only available on certain Blackberry Phones and one of the LG phones, none of which I'm interested in.

I have heard of the Android app Kineto which enables UMA, however I read this was only going to be pre-loaded onto certain handsets and only on the Orange network. From this I assume that it's only available on handsets with Orange firmware and not unbranded ones. Since the other reason I wanted to leave was branded handsets, this might present a problem.

On that note, how well does the UMA calling work anyway? (And why is nothing ever bl**dy straightforward when choosing a mobile phone contract!
