The big takeaway is that all the US-based carriers except for T-Mobile are crooks.

This was a Sprint ad that got pulled right away. If you watch it you may understand why.
Disclaimer: I'm a T-Mobile customer

As if you need another reason to drop AT&T or Verizon. Not only do they rip you off, lock you in horrible contracts, sell you locked phones, etc. They also invade your privacy and track all the internet browsing you do through their network.

@danieljllo2 If you were thinking of buying a #Sprint #iPhone4S because it comes SIM unlocked, it's too late, buddy http://t.co/8THyVd3p
