|What Happens After You Unlock Your iPhone?|
I wanted to know exactly what happens after you jailbreak and unlock your iPhone. I mean, what exactly happens to your songs, your apps, your compatibility with itunes, your ATT phone service, everything? I couldn't find the answer anywhere. So i unlocked my iPhone and i'm going to tell you.
Nothing happens.....thankfully at least nothing happened to my data, my phone service or the way my phone worked. and you can always reset your iPhone back to factory settings ( although i think that resetting your iPhone back to un-jailbroken condition may delete content on your phone-you should check with someone else first, as I have never reset my iPhone) THE INFORMATION IN THIS ARTICLE IS BASED SOLELY ON MY OWN EXPERIENCE, YOU MAY HAVE DIFFERENT RESULTS WHEN JAILBREAKING OR UNLOCKING YOUR PHONE, SO PROCEED AT YOUR OWN RISK.
jailbreaking allows you to install apps that are not in the appstore and allows you to do other modifications to the iphone that you can't do otherwise, such as unlock the phone. you can't unlock the phone until you jailbreak it first. unlocking the phone allows you to use a different carrier such as Verizon or T-Mobile or a carrier in a different country such as Vodafone. You don't need to unlock your phone unless you want to use a different phone service provider. If you want to use your phone while on vacation in a foreign country, without paying crazy fees to ATT, then you will need to jailbreak and unlock it and then you can buy a prepaid SIM card for cheap in the foreign country and put it in your iphone and make calls and in most cases use your maps and the internet and emails etc. when you get back home you can take out the foreign sim card and put your ATT SIM back in and everything will be back to normal. I will make another post about using the iphone in a foreign country later.
I have an iPhone 3G. I Had already upgraded to the 3.0 software using the regular apple update through itunes. I am under contract with ATT in the United States. But I was going to Spain and i needed to have a phone and internet access over there, so i needed to unlock my phone so that I cold buy a SIM card in Spain. I'll tell you all about that in a different post. I jailbroke my phone using redsn0w from http://blog.iphone-dev.org. then I unlocked the phone using the ultrasn0w app downloaded from cydia (the appstore-like app that gets installed when you jailbreak your iphone). i'm not going to explain how exactly it is done because there are instructions all over the internet for that. what i am telling you is what happens after you jailbreak and unlock. providing you follow the instructions exactly, after you jaibreak your iphone, you will still be able ti sync with iTunes, you will still have all of your movies and songs and apps and contacts and emails and everything. your phone will still work the same way with all the same features as it had before unlocking. your phone calls will still work with ATT just like before and you will still be in your ATT contract making and receiving calls on the same plan as you had before. you will still be able to update your phone to the latests apple software (DO NOT UPDATE YOUR IPHONE AFTER UNLOCKING UNLESS http://blog.iphone-dev.org SAYS IT IS OK). turn off auto-updates for your iphone in itunes. the only difference you will notice is that there is an app called Cydia on your phone now. If you open it, you will have access to more apps such as the one you use to unlock your phone, called ultrasn0w.
In order to unlock your iPhone, after it is jailbroken, you have to open up the cydia app, add the "repo" (it's like a tracker for the iphone dev team's unlocking apps- right now it is repo666.ultrasn0w.com) to the list of repos (repositories) in cydia and then you will be able to find and download and run ultrasn0w on the iphone. again there are lots of instructions in other places about that. After you run ultrasn0w, there is no indication that your phone is unlocked as far as I am aware. no messages saying "congratulations, you have unlocked your iphone". you can only assume that it is unlocked until you actually take your your ATT SIM and insert another. if you don't take out your ATT SIM card, it will still work just like before. you can still make calls just as before. As I said, nothing happens to your phone. I will list the only changes one more time in a simple list format. After you jailbreak and unlock your iPhone with redsn0w and ultrasn0w, these are the only things that are different. 1. You will have an app called Cydia on your iPhone 2. You can use a SIM card from another carrier besides ATT in your iPhone * you should not update your iPhone to 3.1 software or anything else unless http://blog.iphone-dev.org says it's ok ** some people report a sluggish feel to the phone after jailbreaking, not me - everything is the same as far as I can tell. yes, I was able to insert a SIM card from a cellular service called YOIGO in spain. they had the best rates fro what I wanted to do and everything worked fine, including calls and 3G internet service. I will write another article on the details of getting phone and internet service while in Spain.
please don't email me if your phone doesn't work after unlocking or with technical questions about jailbreaking or unlocking or about ethical arguments for and against doing it. I'm a musician, not a techie. it was easy for me to do by carefully following the instructions on the professional's websites. the only reason I unlocked my phone was so I could use it on a business trip to Spain. ATT charges a minimum of 1.29 per minute for iPhone calls from Spain to the U.S. and $15.89 PER MEGABYTE FOR DATA USAGE. it is unbelievably expensive. if you are traveling outside of the U.S. and your ATT SIM card is still in the iPhone, set the iPhone to Airplane mode to avoid crazy data charges. Better yet, just remove the ATT sSIM card. your iPhone will still work without it. It basically becomes an iPod Touch at that point and you can listen to your songs etc. But the GPS and the other apps that need an internet connection won't work unless you are on WiFi. Obviously this is no goos if you want to use the iPhone maps app for travel guidance. You will need a 3G or other cellular data plan for that. if you want to use your iPhone with WiFi whenever it is available, then go into the settings and turn off anything related to cellular data network and 3G etc. hope this helps a few people
