  • UnlockIt - The APN Changer for iPhone


    Since the iPhone was first released, there has been a constant struggle between Apple and its end users with regards to which carriers and tariffs are compatible with the iPhone. Software unlocks such as ultrasn0w have ensured that iPhone owners are free to choose which carrier they would like to use but once the phone accepts the sim card - that isn’t necessarily the end of the battle.

    Many carriers have data plans which differ from one another, and some are less compatible with the iPhone than others. Unless users are on an “iPhone Data Plan” it is generally hard to reason with their carrier. The settings which carriers send to iPhones are usually specific to the iPhone plans and as such are non-compatible with other plans.

    For example, I have a Blackberry and an iPhone - I don’t want to have to take out two different contracts for my two separate handsets, nor do I wish to call up my carrier and wait 24hrs whilst they change the data plan each time I want to change phones. So what can I do? This is where UnlockIt - APN Changer comes into play.

    UnlockIt is an online service which doesn't require the device to be jailbroken or unlocked. Simply navigate to the site and input the details you wish to use on your phone and APN Changer does the rest. What you are given is a signed profile which your phone automatically installs. It is the equivalent of sending yourself carrier settings which you have customised.



    When I was searching for ways to use my Blackberry sim in my iPhone I was told by countless people that it would either simply not work, or I would run ridiculously high charges for data because the iPhone wouldn’t be using the Blackberry/RIM APN to send/receive data packets.

    A quick check of my carriers smallprint informed me that they use three different APNs on their Blackberry data plan, two of which had unlimited usage included. One of these two was the Blackberry APN, the other was simply Mobile Web/Wap. It was then a case of simply using APN Changer to set the APN to the latter, and I haven’t been charged since.

    In theory, APN Changer can be used to grant much more freedom to iPhone users, particularly when combined with an unlock such as ultrasn0w. Some carriers for example are stopping Unlimited Data plans for the iPhone, however other plans still get the Unlimited Data. Using APN Changer users may switch between phones and data plans easily.

    So although the battle continues between Apple and their end users, APN Changer helps to make life easier for people being pinned down by their carriers and forced into an iPhone contract. APN Changer is currently compatible with all iPhones and has recently been updated to support iOS4.

    With built in settings for most carriers, a custom APN Changer and the ability to set a blank APN which effectively disables data use - UnlockIt APN Changer certainly helps to set free thousands of users who have issues with their carriers.

      I already tried searching. I googled it and it just took me to the main site....which was down. Searching on here is not one of my things as anything I find would probably be in computer-lingo and I wouldn't understand it anymore than I did the OP in this thread. Not to mention I'm posting from the mobile-version of this site from my phone and I don't see a "Search" button anywhere.

      And explain to me how trying to get clarity on this thread and it's details is a stupid question. Please. The "English" comment was just a JOKE..... Meaning I don't understand all this hi-tech computer talk as well as most of you all do.

      I appreciate the effort.....really I do, but apparently the post right below yours just crushed any hopes I had for using this. I'm an AT&T customer.......unfortunately.

      Would this allow me to share my iPhone 3G data plan with my iPad?

      (Home net, iPhone net, work net, iPod net, etc, etc). Is this a rip-off or what? Are we being way-overcharged for internet access?

      Hahaha. It's time to revolt.
      I wouldn't mind it much if AT&T was actually better than what it is now. They claim to be the fastest, but it seems that every Verizon smart phone that comes out beats the iPhone in a speed test.....een now with them both having 1ghz processors.

      Their text plans are ridiculous to. Jumping from 200 to 1500 is ridiculous. They need to double their $5 one to 400 messages and throw in an intermediate 800-message package for $10. I mean how much does it cost AT&T for each text sent?

      I just gave my dad my old 3GS. He only paid 11$ for his plan on his old BB. I put his SIM in, unlocked it via ultrasnow, then disabled data (fake APN). Now lets hope my dad doesn't get a fat phone bill.

      Experts - did I do the right thing?

      A recommendation my friend: Google Voice + GVmax.com + BeejiveIM = instant win free text messaging.

      So with this I can put in an IPad SIM in an IPhone and have the APN changed to the IPad APN and use an IPhone for data only?

      Yes it works great. You might need to weigh how often you use the phone for calling. I am finding that the voip apps have great sound quality but so-so reliability.

      No catch, other than being at the mercy if Google servers ever have an outage (which has happened time to time even with gmail).

      Sounds good, I when I had the iPhone I hardly ever used it for voice as I have a work phone for that. This might work perfect for me.

      So,

      what I did was take out my dad's BB pearl SIM card and put it in my old 3GS. Prior to APN modification, I JB and unlocked using blackra1n and ultrasn0w. After, the phone was able to use its phone function: call&text etc. I then read this post and changed my dads profile to a disabled data one or an invalid one. MMS didn't work. I then did APN changer to ATT profile and now MMS works. I don't know if my dad is going to get charged a lot. Any help?

      Yep that's it!! This gives data access on the iPhone for simcards the iPhone normally would not allow ( like ipad sims, or other data only sims, or sims that the iPhone won't seem to accept to use data on), this is not a phone unlock, just opens the ability to change the apn (access point name) for the use of data on a sim ( provided this sim works on the iPhone , it does not give the abilty to use any simcard on the phone or jb's the phone. ( please correct me if I am wrong tho, I haven't used the program, but I'm pretty much 100% sure this is the case)
      But If you have access to the 'cellular data network' icon in network settings you can change the apn there too. If your phone is originally from an Australian carrier there are cydia apps that reveal this icon ( in cydia or rock do a search on GPRS, choose your carrier and vwaalla!!), generally an official unlocked phone is meant to have access to the apn through 'cellular data network' but since ios3 came out apple and the carriers in oz put a stop to this access for official unlocked 3gs, but neither company in there customer support knows why or how as their online support still after 1year shows that it should still be available to access after officially unlocking the iPhone 3gs, they just throw the blame on each other.
      I use an ipad sim on an unlimited data monthly prepay ( no lockin contract) for my iPhone (or now is an ipad nano)

      Without this program and if you have an unlocked phone via ultrasn0w is there a way to change the APN with an AT&T SIM in it?

      So mike your response to gmb is telling me you're not allowed to use a different, same carrier non iPhone, SIM in the iPhone for ATT and TMobile.

      If u have access to the "cellular data network" icon in settings>general> network
      you can change the apn there. u may find something in cydia, not sure for other countries carriers tho, I actually accidently stumbled upon the cydia vodafone GPRS app by accident just wondering through cydia, downloaded it and then realized what it was.
      There is also another website which does the same thing from their actual site, but I can't remember the address, just google "change apn on iPhone" and u should find it.

      So AT&T wouldn't know by my imei number that I'm using an iPhone?

      I don't want to change my imei number and I know it's not allowed to talk about imei number changes so I'm gonna stop right now.

      Using this, will an iPad sim be able to be used in a iPhone 4? Or does it need to be unlocked?
