Help! How can you tell if someone has blocked you from sending text messages on the iphone4? I sent a text message from a previous "conversation" and it appeared to go thu. However a few hours later my iphone went off alerting me of a new text msg (ringtone went off thats how I knew). But when I looked at my phone there was not a new text message.
Could it be that the person blocked me and because I have an iphone (so does the person I sent the text to) does it not let you know that you were blocked??
Thanks for any help!
