Is there any app, even one I can pay for, that allows me to block a text message? Something like do not disturb. I used to have my phone jailbroken but since I updated to iOS 6 I haven't bothered so I cannot get a cydia app. I want to block text messages from a few people (just for a few days) but still want to be able to get messages from other people. Is there an app for this? Thanks!
