a screen run is when someone sells you a real legitimate iPhone and shows you it's working but it doesn't function properly such as no service or really slow lag time . These kind of problems maily occur when "jailbreak hackers/developers" try to get rid of their iphone for cheap. Be careful where or who you buy your stuff from! Remember if the deal is too good to be true, it probably is.
yes. once an iphone is universally unlocked it will work.
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.
Yes it will. I have mine with Centennials service
Some one are unlocked, some one are locked! if you bought it from Japanese and bring it to other country, it could not used.
No sorry the Iphone uses a different type network than the Nextel service.
Unlocked smartphones can be bought at phone stores, where, besides selling phone plans they also offer the possibility of buying unlocked smartphones such as iPhone or BlackBerry.
Yes. The iPhone 5 works well on European cellular bandwidths.
unlocked only means it can be activated on any service, not that the phone is any better, when the iphone came out it was only available on one service, unlocked means you can activate it on any service
if you bought if with orange or have jailbroken and unlocked it then yes is should work fine.
no, due to licensing rules with Apple the iphone is available only on o2. There are rumours that the iphone 3g will be appearing on orange and t mobile at the end of the year. To be fair though, unless orange is the only network you get signal with then move to o2, they have 2 things, 1 called customer service and 2, best of all you can ring them without setting aside an hour of your day.
In theory, yes. T-Mobile is actually the carrier for the iPhone in Germany. Keep in mind, however, that unlocking an iPhone completely voids its warranty, and if anything happens to it, the only recourse is to purchase a new iPhone. Apple will not service a broken iPhone if it is unlocked.
Yes, and unlocking it allows you to use other service providers.
