Does updating my iPhone delete my text messages?

I'm downloading ios 6 and I want to know if I install it to my phone, will it delete all my text messages? I know it's weird question but I'm OCD about it.

No it didn't delete mine

It deleted mine.

And I had things I needed on there.

It depends. It deleted mine and I had tens of thousands of text messages. I have an iPhone 4 and since I updated to iOS 6, it won't restore from the back up I have. However most people didn't have that problem.

  • Will updating to iOS 7 delete text messages? I know I'm late updating and all but I haven't had this phone long, since I replaced my old one, but I have an iPhone 4 and I'm planning on updating to the iOS 7.0.4 that is available. I have text messages that I've kept for a while because of information or I'm too sentimental for some to get rid of them (yeah, judge me) but I don't know if updating now will delete those (I'm hoping not). Also, will it delete my contacts? I hear it has for some people.
  • Will updating my iPhone apps affect my phone speed as how updating the Operating System (OS) will? Currently I'm using the iPhone 5s on iOS 8.3 I know if I were to update my phone to the latest OS I may notice some slowdown on my phone's performance, since it may not have the "muscle" to handle certain functions. Many apps now are optimised for iOS 9 and/or the 6th generation phones. Will my 5s' speed performance slow down if I update my apps? Will the app's performance slow down?
  • When I receive text messages with emojis from an iPhone, why do the messages only appear partially? My phone is a "Verizon Samsung Intensity II" slide phone. (Also it's blue but that doesn't matter.) Also, if I'm included in an iPhone group chat (spoiled rich friends, but not snobby…), I get each posted message as a separate message, so I'll end up randomly with 67 unread messages clogging up my inbox.
  • Iphone will not let me delete individual text messages! Solve please? I have iphone 4s and i do not want to delete the whole convo just certain messages. As in if I sent the same message twice. I go to edit the trash and forward options are greyed out and I can't delete anything. I do not want to delete the entire convo.
