None, unfortunately. Due to all the hot air they are filled with, they float too well to sink in water preferring instead to form a layer, or crust on the surface, like pond scum. It is only the quantity of BS they also contain that prevents them from floating away completely...
If you get an email telling you that you can catch Swine Flu from tinned pork then just delete it. It's Spam.
It's really not the same. It's quite reasonable really, a network gives a discount on the phone in exchange for signing up to a contract they don't want you cancelling the contract and taking the phone to a different network so the phone is locked. Once the contract is over they'll unlock your phone and you can take it wherever you like.
If you don't want a phone that's locked to a network then you'll just have to pay the full price for it.

They already have a solution to that. You pay about $400 if you want out of your contract (I think that value goes down over time). I suspect the real reason for preventing the phone from being unlocked is so you can't use a SIM while you travel in a foreign country to reduce the cost.
Sure and it is unenforceable so it undermines the credibility of the legal system (I know it has no credibility now), undermines to confidence of the enforcers (police, inspectors, whoever) and reduces to effectiveness of society.
I know it is only a small thing but these stupid bastards need to be taken out and garroted, waste of a good bullet!
Never underestimate the power of human stupidity
