I'm after a Samsung Galaxy S2 at the moment. I was initially after an unbranded handset, after having a branded HTC Hero which Orange took ages to get round to upgrading.
But then I read that an unbranded phone wouldn't run UMA / Signal Boost. I currently have a ropey signal in my house, so that could be handy.
On the other hand, it seems that Orange are already lagging a bit with the minor updates, and if ICS comes through, I can see them hanging onto it for months like they did with 2.1 for the Hero.
So, if I buy an Orange branded phone, is it fairly simple to back up the Orange ROM / Firmware and stick on unbranded if I like?
