If I buy an unlocked iPhone4, would I be able to update its system using any compatible network?

Does anyone know if one can be able to upgrade an unlocked iPhone4 to a newer OS version available using any network, say T-mobile?

If the iPhone has had an authorised unlock (by the carrier, or is a brand new unlocked model) you can use it with any wireless carrier in your region (and in some cases the world). If it is an unauthorised unlock (jailbreak) updating or restoring the software will lock it again and you will need to contact the carrier yourself to unlock it.
Be really careful when buying second-hand "unlocked" iPhones because most are done with a jailbreak.

    Oh those Canadians, you just have to take what they say with a grain of salt.
    The warranty on the iPhone, contract or not, is not world wide. If something happens to your iPhone I seriously doubt wherever you are in Europe that they stock Canadian unlocked iPhones. Worse, if you take it to an Apple Store in a country where the iPhone is locked then they can only replace it with a locked iPhone from their supply of replacement phones. If it is with a different cell provider than you use well, that's just too bad.
    You would either need to return to Canada for service or send it to someone there who can take it in for you.

  • How can I buy an unlock iPhone4S in USA during my trip?

    I an not sure whether this post should be in this community or not.
    I will have a trip to USA next week. It's cheaper and more convenient to buy an iPhone in America and I wanna get one during my trip. My friend said it is not 100% sure that you can buy one in a retail store without a booking. However I can't find any way to do booking. I know there's a pick-up service but it is not suitable for me.
    So I want to know how can I buy iPhone in my trip? I will visit the Fifth Avenue on 25th Jan. and I want to know without a booking can I buy an unlock iPhone4S?
    Thanks for help.

    You can call them to see if they have some in stock.  The last time I visited an Apple Store they did have unlocked iPhones in the store, but stores inventory vary.
    After looking at this it seems that they do not have any in stock at the Fifth Avenue Store.

  • If i buy an unlocked iphone4s in america and get it shipped over will it work in ireland? Im meteor btw.

    If i buy an unlocked iphone4s in america and get it shipped over will it work in ireland? Im meteor btw.

    Keep in mind that you're going to have to have somone order it for you and have it shipped to themselves, then ship it to you. The unlocked 4S can't currently be purchased at retail in the US and apple.com will only accept a US credit card with a US billing/shipping address.
    Meteor is listed as a supported carrier, so you shouldn't have any problems on that point.

  • I have an iPhone4 from au KDDI in Japan, I want to use any carrier sim here in Philippines, what if au KDDI in Japan is not offering unlocking iPhone. What can I do?

    I have an iPhone4 from au KDDI in Japan, I want to use any carrier sim here in Philippines, what if au KDDI in Japan is not offering unlocking iPhone. What can I do?

    If you are a gaijin (I'm a gaijin too) never take a iphone in Japan. Your phone will turn to be nothing more than a paper weight once you are out of Japan. I recently moved to UK and my iPhone 4s which bought from AU is now completely useless. AU does not unlock the phone, there is no option in the net to get the same unlocked too. So I decided to advise those gaijins in Japan to never waste your money spending on iPhones in Japan and if possible never get trapped into the services of AU.

  • HT4972 if i want to update my system using a new itunes library would my old data go

    if i want to update my system using a new itunes library would my old data

    I was concerned about this when I got my new iMac last year and had to say goodbye to my old emac (sob!) In the end I had to copy all my tunes etc onto an external hard drive and transfer to the iMac. I think I had to do that in this scenario, but now I have a new iPad when I connect to iTunes on iMac it shows that I can sync and transfer the iTunes stuff if I wanted. I would be extra safe and back up the old tunes first on an external disk, esp if you have loads. I back up my stuff even now from my iMac iTunes as I don't even want to think about how much the stuff is worth!!

    Actually it depends on the Bandwidth of the network they will be using. You can see a list of tech specs on the iPad website.

    Hacking the iPhone is against Apple's license agreement for the iPhone, is not supported by Apple directly or indirectly via these discussions, and removes the built-in security included with iOS making the iPhone as vulnerable as insecure android devices.

  • Can I buy an unlocked iPhone 5, activate it in the US and then use it in Italy?

    I am an italian guy studying in the states and I want to buy an unlocked iPhone 5 here in the US, but I’ll go back permanently in Italy in May.
    1429 CDMA model should well with my ATT sim since it covers all GSM features, right?
    Then back in Italy I just need to put in a nano sim from my italian carrier and that’s it…it should work.
    Just one more question….is it better to activate the iPhone with US sim or Italian sim i have on my iPad 4?
    Although I don’t have internet pack in neither of sims, thus I use WiFi to activate it, but i don’t know if it’s better to put italian sim for some reasons i don’t know…Anyway i’ll use another sim back in Italy (sim in iPad is not my “official” number, i just use it for data pack).
    I hope everything is clear and easy to understand.
    Thank you!

    Matter of fact i do not need LTE in US, i just need normal 3G connection, and there shouldn't be any troubles with ATT for that, right?
    Correct, but AT&T will require you sign a contact for new service, whether your phone is unlocked or not. They don't do pay-as-you-go for the iPhone.
    Thus 1429 CDMA won't work with LTE in Italy?
    Only if roaming with Verizon, otherwise, no.

  • If i buy an unlocked iPhone 6 plus on Apple online store, will it work with CDMA network?

    I see iphone 6 unlock is A1524, but it has 2 versions, GSM and CDMA, which one will i get? CDMA? many thanks

    I clicked the "Learn more about the unlocked iPhone" link (just below the words "Unlocked and contract-free" on the store page: http://store.apple.com/us/buy-iphone/iphone6 and it displayed the following in the fine print at the bottom:
    An unlocked iPhone may be activated on supported GSM carrier networks

  • How do i unlock my Sprint iphone5 with IOS 7.4 0 to use any network here in the U S?

    How can i unlock my Sprint iphone5 with IOS 7.4.0 to be compartable with other service providers here in the U S?

    You can't. Sprint phones can be unlocked ONLY for use on non US carriers. They can not be used on any US carrier other than Sprint. If you want to use a different carrier in the US, sell the phone and buy one you can use.

  • Would I be able to update my phone early if the upgrade date is for October 2014?

    I currently have a iPhone 4 and I absolutely hate it. It's old, keeps freezing and crashing, plus I can't even get iOS 8.
    Is there anyway I could upgrade to the iPhone 6 now while keeping unlimited talk/text? If I have to pay a fee how much would it cost? My contract ends on October 27th.

    Dial #UPG from your phone; your upgrade date may have been moved up:
