The updates are depended on which operator the phone was bought from not what sim you have in it.
You sure about that? Wouldn't that imply its operator locked?
Maybe there are some additional factors, because madzta was not getting updates and I was, even though be both bought it through Vodacom. The only difference is that i have an MTN sim and he didn't.
I did a fiddler intercept on out going calls and the datapacket interestingly had strings that mentioned MTN, Vodacom and Cell-C in it.
Oh well, you're probably right, and I don't know enough to argue, I'm just glad I got my update3.
One thing though GD3 on my Samsung halved my battery life :-(
