I have previously unlocked my o2 phone, if I carry out a factory reset will it relock itself?

I am thinking of selling my iphone 4, which originally came from O2. I previously had it unlocked once the contract ran out. I am thinking of selling it, but will a factory reset "lock" it back to O2?

That depends on how you "unlocked" it. As bhazel stated, if it was legitimately unlocked by the carrier, and restored using iTunes so that you got the "Congratulations, your iPhone is unlocked!" message, then you can update it and it will remain unlocked.
If you took it to a shop on the corner and had it "unlocked" it was hacked. Not only will it not remain unlocked if you update, it may become completely unusable, even with the carrier it was originally locked to.

My iPhone 6 order was canceled without my permission and without reason or explanation. I have had a verizon cell phone for 13 years and have gotten your cable/internet/phone when i moved out on my own because i had been so happy with the experience i had

I have had a verizon cell phone for 13 years and have gotten your cable/internet/phone when i moved out on my own because i had been so happy with the experience i had with the cell phone service. i ordered my new iPhone 6 on October 6th along with my husband. i was told by the sales associate at the vierzon store where i placed the order that it would ship a week before halloween. instead of a shipping confirmation, i received an email a week before halloween letting me know that my order had been placed on 10/24/14. i thought this was weird, but figured i could weight another week or two, no big deal. my husband got his phone in the mail yesterday. still no sign of mine. then this morning i got an email letting me know that my order was cancelled and if id like to place another order for a phone, then i can go back to the store and do so. why would i want to go through another month of this??? verzon lost my order. i never canceled it and i am beyond annoyed. i am looking to switch my entire house to another provider. this is ridiculous.

i did not get any reasons or explanations. the email just stated that my order was canceled and that it won't be posted to my credit card (i have more than enough to cover the cost, so that is not the issue). also my husbands phone was paid for from the same card moments before me. my balance is always paid automatically and on time. so that couldn't be the reason either. that's what so frustrating is because they didn't explain what happened. this is what the email read exactly:
"This email is to confirm that your order has been cancelled; you have not been billed for this merchandise.
If you would like to place a new order, you may do so by visiting your local retail store or going online to www.verizonwireless.com.
Business customers should refer back to their local Verizon Wireless Sales Representative if you have any questions or would like to place a new order.
Thank you, and we look forward to your business in the future.
Verizon Wireless"
it almost feels like its saying that i canceled it and that this was to confirm that i did. but i didn't cancel anything.

Various applications are crashing on my iPad, including Facebook, Safari, and TwoDots, along with others. I have tried all of the solutions I found except doing a factory reset and downloading the backed up iCloud version of the iPad. What do I do?

When I try to open or access some features of these apps, I get the
loading sign, then the screen turns black, and it takes me to my Home screen. Sometimes this also occurs when opening links in Facebook and Safari, and some of my Apps are completely useless as a result of this. I have rebooted thrice, re-downloaded the apps, and tried clearing them from the queue, nothing works. Also, I have noticed that the background of the home screen is oriented incorrectly at times, (background is portrait whilst the rest of the screen is landscape) and I'm really at a loss. I assume it's a glitch with iOS 7.1.1... The iPad is a 4th generation and has shown no problems until recently, around when I updated. I'm not jail broken or anything, but my Wal-Mart warranty has expired. What should I do?

IMO, you answered your own question with your lead in about backing up, erasing the device and restoring from the backup. That's what I would try next.
If that doesn't work, I would backup with iTunes, and restore the iOS again using iTunes. You can't restore the iOS by simply erasing the device. You have to use iTunes in order to reinstall the iOS.

Hey majims,
Thanks for the question. I can imagine how frustrating that may be. The following resource should help you learn what to do if your device is not responding or starting up past the Apple logo:

I have a brand new iPhone 4GS from Bell Carrier, I want to have it unlock for my Roger's carrier, is this possible?

I have my step-son's iPhone 4GS from Bell Carrier, he upgraded his phone, I have a 4G, and I contacted Bell in order to have my phone unlocked so I can replace my phone with the 4GS with my present carrier of Roger's. Bell customer service informed me that they are no permitted to unlock iPhone and directed me to Apple.
I am a bit confused, these are very good phones and now I cannot use it because it is locked with a carrier, obviously the phone is paid for if Bell offered the free upgrade. Why can I not be able to use this phone and put my SIM card from Roger's and use it, instead we are disposing of good equipment that is obviously bad for the environmnent.
It is very simple, again I believe Bell is monopolizing, they want me to take this phone and get a plan with them, however, the story is that Roger's originally unlock the iphone for $50, and I bought a Bell SIM car dr $25.00, but I cannot pay Bell to do the same.
Can Apple authorize the unlock of this phone when the carrier refuses to do?

Apple does not unlock phones. Only the original cellular provider, in this case Bell, can authorize unlocking. They are passing the buck for their decision to not provide unlocking.

HT201406 My phone keeps trying to facetime randomly during phone calls, it will also mute itself and put itself on speaker phone. Anyone else have this problem? I did the factory reset and I am still having issues.

My iphone 4 will randomly try to facetime, mute itself, or put itself on speaker phone during a phone call. I did the factory reset, but I am still having this problem. Does anyone know what may be wrong, or has anyone else had this problem before?

I have the iPhone 4s on Verizon and never had this problem until I recently updated to iOS 7.0.2. I have the same case on it for several months. Yesterday, when I was talking on the phone with someone, it appeared as though I lost the call. But when I looked down at my phone, it was trying to Facetime with someone in my contact list. It happened again today. Different person, but both people have names that start with "A", so they are at the top of my contact list. Very frustrating! So, obviously updating to the latest iOS either did not help or was the cause of the problem.

If i factory reset my iPhone 4 will it lose the sim unlock that the carrier applied?

Hi, I have upgraded to the iPhone 5 and am looking to give my current iPhone 4 to a family member, I originally got the phone through Orange but after signal difficulties had it opened to any network by Orange. I want to know if I do a factory reset will it lose this and will I have to have it done again?

If you are the original owner, and Orange is the original carrier, and you requested an official unlock then yes, whatever happens you device should remain unlocked, provided that the device was never "touched" by any other unlockers...

No wifi, have tried clearing all caches, factory reset? any more help welcome

You can try the other suggestions of the following. However, it is frequently a hardware problem and an appointment at the Gnius Bar of an Apple store is in order.

Jailbroken phones can not be discussed here.
It's highly likely that it is now bricked. The jailbreak most likely did permanent damage. There are lots of reports of previously jailbroken/hacked phones that become unusable when attempting to apply a legitimate unlock.

I just got an apple at&t iphone 4 and I have it unlocked. But I want to connect it to t-mobile, so I trimmed my sim card and once the phone was unlocked I inserted the sim and it says no sim, activation error. What can I do to fix this? What is wrong?

I have been given an i phone 3 that was on O2. Had it unlocked and placed my vodaphone sim in. I live in Spain so on getting back here tried to connect it to my computer,updating I tunes like stated in guide. A message comes up now with no sim, no connect

I was given an I phone by my son in law, he was on O2. I had the phone unblocked and placed my vodaphone Spanish sim card into it. All worked well until I connected it to my computer in Spain. in the instructions they advices to update my I tunes which I did. A message came up on the computer sayin no sim and my phone became locked again. I now have a useless phone as cannot get a screen. I don't know what the serial number is as can't access details from the phone and have not got the box. Can anyone help. I paid £25 in the u.k last week to have it unlocked.

Chances are you got ripped off. If you didn't have it unlocked by O2, you had it "hacked". Updating it has re-locked it. ONLY the carrier it is locked to can unlock it. If you're not physically in the UK, your chances of getting it unlocked are near nil from what others here have stated.

going to Italy in the fall Have read that all European phones are sold unlocked. I don't want to spend a fortune on roaming. Is it better to unlock this phone and get an Italian carrier upon arrival or should I just buy a local throw-away phone when I get there?

HT3529 I bike to work and when I get a text while biking, I want Siri to read me the text so I don't have to pull over. However Siri tells me I have to unlock my phone first but I can't as it's in my pocket. Any solution?

I want to be able to be the hands-free equivalent on my bicyle as drivers are in their cars. I bike to work and wear my right headphone to I can answer calls while riding. I want to be able to do the same for texts that come in but when I try to get Siri to read me the incoming text, it tells me I have to unlock my phone first. But my phone is in a pocket! Is there a setting I can change so that I can be more functional while biking?

Try deleting the old backup.
Settings>iCloud>Storage & Backup>Manage Storage, tap the device name and on the resulting screen, scroll down and tap on Delete Backup.

Sounds like the device was dropped at some point and damaged as a result.
Take it to Apple for evaluation and a replacement.

I paid early termination fee two months ago to Verizon and am now out of the country. Am trying to unlock the phone but the local guys say they are not able to. I see from the blog here that iPhone 5 comes unlocked. Is it true?? Do I still have to unlock.

Thank you for reaching out to us, Texasman. Sad to see that
you have left the VZW family, but it is definitely awesome to be able to
travel! Regarding your iPhone 5, the phone is unlocked for international usage.
Just need an active local SIM card that is compatible with your iPhone. Your local provider
may need to configure some settings under Cellular, but it should pick up signal. Just in
case, make sure that Settings>Cellular>Roaming>Voice & Data are
active.
