How to lock my text messages?

I know I can lock my phone, but my text messages. I have an Iphone 3G. I let my parents and friends use my iphone, but when they do I don't like them going through my text messages. So can I Specifically lock just my texts?

That's not possible, unless you jailbreak your iPhone.

Nope not unless your iphone is jailbroken

  • Why is my iPhone5 sending some messages as iMessage and others as Text Messages? I understand that messages are sent as Text Messages when there's no signal or poor Wi-Fi connection. However, I'm successfully texting some people using iMessage but others (still iPhone users) as Text messages. The other person will send iMessages and then my responses will be sent as green Text Messages.
  • 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 lock button broken, is there any alternative to lock iphone? My iphone 3G lock button is totally damaged and is out of warranty and I can't afford to get it repaired. I was wondering is there any app which can convert "silent" button to lock button. Or may be an app on which i can manually lock the device. By the way my Iphone is jailbroken, and "accessibility" is not accessible.
