Yes, wether the iPhone is legally unlocked or jailbroken-unlocked.
You can find out more information on the iPhone 4 from friends, by asking someone at the store, or by looking online. I have unlocked the iPhone 4 by just asking friends and looking it up online.
I can think of two stores which might have this unlocked iPhone 4 for you to get there. One is target. The other is best buy. The 3rd is or could be radio shack.
yes it can. You can hack it to unlock it, or else in some country you can unlock it legally. For example in france.
in the UK the iphone 4 unlocked 16gb is 499 british pounds and the 32gb unlocked is 599 british pounds in the US the iphone 4 locked by AT&T is $199 and the 32gb locked by AT&T is $299. The US prices indicate a contract phone price, that is not the same as an unlocked phone. The iPhone 3GS 8GB is $474, the iPhone 4 16GB is $649 and the iPhone 4 32GB is $749 with no contract. :)
You can visit apple.com or visit a local apple store for unlocked iPhone.
Just got back a month ago from the Philippines. I have an unlocked US version of iPhone 4 running iOS 4.0. Worked like a charm. Hence the word "unlocked" so yeah it will work just fine. Unless you're iPhone 4 is running iOS 4.0.2 and above (which the latest is 4.3.1), then you're out of luck, that is, you cant unlock your iphone through Ultrasn0w. If you plan to go there soon, probably try GEVEY SIM for iPhone 4 as this hardware mod can unlock iPhone 4 on iOS 4.1 to 4.2.1. Retails about $70 but eBay has cheaper ones. But if you are not in a hurry, the Dev Team is trying to crack the iPhone NCK Key that can permanently unlock your iPhone 4 for life. You can wqit for that too. Good luck! iPhone 4 16GB Black iOS 4.0 Jailbroken using jailbreakme.com Unlocked using ultrsn0w 1.2
If you have the iphone 2g(the one with black and white back cover),then the answer is no..But if you have iphone 3 or 3gs,they will let you upgrade the phone to iphone 4 as long as you pay for the new iphone 4. Hope this Helps. And by the way,if the iPhone is Jailbroken,or unlocked,then they won't let you upgrade it. so make sure you restore your iphone before you trade for a iphone 4
Yes, just either slide the little bar, or type in the password
Unless its an iPhone then it would be no.
You can check to see if your iPhone is unlocked by inserting a SIM from a different service provider and try to make a call, if its successful. Your iPhone is unlocked.
eBay or Craigslist
