Besides at&t, Verizon, etc. Which other companies can activate an iPhone 4?

I heard someone said that Boost mobile would do the job, but then I investigated and it is not true. What other companies do activate an iPhone 4?

Sprint and virgin mobile

If you jailbreak your iPhone you can use any cell plan. But if you want it to have a warrany you'll have to go with AT&T or Verizon.

  • Would it be okay to put logos of other companies in without permission in my art? I'm joining this nationwide art competition in my country with the theme of "consumerism." I'm planning on putting an iPhone on my artwork but instead it will say iDiot. Will designing it in a slightly altered way avoid lawsuits? Do you think the competition will reject my entry if they saw a representation of the iPhone? It will not be the main object in my piece, just a little accessory. Like really small.

  • Is there any other star gazing apps besides SttarTracker Lite? This app totally sucks and is one of the worst I have have ever used, it doesn't locate the constellations correctly and has very bad compass bugs, so what is a an actual GOOD stargazing app.
  • I bought a verizon iphone 4 the other day.and i tried to activate it? I bought a verizon iphone 4 the other day. And i tried to activate it and verizon told me that i couldn't activate it because its already activated with another account. What am i supposed to do? They said that the phone was already unlocked so i'm supposed to be able to use whatever carrier i wish but i'm so confused and i need answers FAST. How can i get this phone working under my own account? I can't put a sims card in it because it doesn't have a sim slot
