Iphone IMEI sim lock: Unlocked?

I bought a used iphone 4 off ebay. Now the seller said it is permanently unlocked. I use tmobile with the phone, So I know that it is unlocked. I used a few websites and checked the IMEI and after i checked my IMEI on a few sites, they all said it was Unlocked. My phone has a software update. So if I update my software from 6.1.2 to 6.1.3 will my phone relock?

I'm new to apple products and I just would like some answers, I don't want to relock my phone and make it un-usable for tmobile.

Please help? I've tried to contact the seller but they aren't answering.

Is Cuba as bad as Americans potray it? Even JayZ and Beyonce went?

As I was watching a video where Beyonce and JayZ went to Cuba, I couldnt help but notice that as the couple walked through the streets of Cuba, many Cuban people and teenagers had cell phones and iphones and were taking pictures of the couple as they passed by. I thought they were communist and werent allowed such luxuries, or are we not told the complete story?

Jay Z made a new song recently, rapping about the lies that the American politicians have been feeding us all this time and shaming them and calling them out on their BS.

Added (1). @Randy: I agree with you but I think the problem doesn't lie with all Americans but mainly Cuban Americans. Cuban Americans keep that embargo alive for reasons like "My grandmother was killed by Castro" or "My property was confiscated by Castro" etc… And Cuban Americans are a powerful lobby group in the State of Florida and Florida being a swing state makes politicians say things like "Viva Cuba Libre"-George W. Bush. Cuban Americans is the reason why this embargo hasn't been lifted yet.

IPad and iPhone Won't Recognize Wi-Fi Network?

I'm in college, and the university has a Wi-Fi network that has WPA2 Enterprise security. I successfully connected to the network months ago, in the fall, and haven't had any trouble with it since. As of this morning, neither my iPad or iPhone will recognize the network anymore. When I attempt to connect to it, it will exhibit all the signs of being connected but safari won't work and neither will apps that require internet connection. A few seconds to a few minutes later, it will just disconnect.

When I first connected to this network, a window popped up telling me my device is registered and to wait a few minutes for my device to recognize the new network. It did, and I never saw that window again. It is popping up again today every time I try to connect to the network, but it has been many hours since it first did this so obviously something isn't right. Any ideas as to what could be going on here?

Virgin Mobile iPhone5 from Canada can be activated from USA?

Iphone users, is it worth the price?

I know you have to buy into a contract with AT&T for two years. I don't even know which plan they have and you have to pay each month, but… After two years contact, you can go month to month or renew for another two years… By that time, you probably will have a new iPhone model… Another expense.

is it really worth it or should I just sick with my prepaid smart phone from Walmart straight talk? Unlimited everything for $45.00.
