Some networks, including O2 and Three, have already pushed out the Ice Cream Sandwich update of Android. So what about owners of SIM-free models? It seems you'll be at the back of the queue.Unusual, to say the least. As a rule, SIM-free handsets are the first to get upgrades, as they don't have to wait for all the network testing that takes place before contract users get an update. However, in this case, Samsung is coming at it from a different angle.The Korean company is waiting for all the networks to roll out its updates to be sure Ice Cream Sandwich is working across the board. That could be a long wait if one network drags its feet.Simon Stanford, VP of telecommunications and networks for Samsung UK & Ireland explained: 'We work in conjunction with our partners to bring ICS to the existing base - that's primarily what needs to happen, whatever network operator that may be. In this particular instance, the open market variant [ie SIM-free] you would expect to come out first.'But he added: 'As an open-market customer you will be on a variety of networks, so it's got to work on whichever network you have chosen.'It makes sense, but it is certainly going to annoy people who have paid out to get these kind of updates first. So when can SIM-free owners expect to see Ice Cream Sandwich?Stanford doesn't offer a specific date. 'We're really pushing it hard over the next coming weeks' was the reply.As for future devices, well it looks like Samsung is going to be carrying on with a similar approach, but the company 'wants to level the playing field so everyone gets the update around the same time'. Makes sense. Let's just hope those updates come just a little quicker than ICS.
