  • Why won't my new iphone 4s send pictures? I just got my iphone 4s and it won't let me send pictures to anyone without an iphone/imessage. I tried restarting my phone, i made sure the MMS setting is on my phone and i even tried reseting network settings and nothing worked. I know for a fact my plan lets me send pictures too. Do you no how to fix this?

  • Why won't my iPhone allow me to send or receive pictures? I have an iPhone 4S and when I receive a picture it links me to the website of Telus(my service provider) where I can look at the picture. Why won't it come straight to my phone? And why can't I send a picture
  • Why won't my iPhone 4 send pictures? I've had my iPhone for a little over a year. It would rarely send pictures. I updated it to the iOS5 recently. People are saying that's why they wot send but even before that it was rare for my pictures to send. I can send pictures to people with iPhone 4s' but not other phones. I kinda think that it might be because it's unlocked and it's tmobile. My family was saying maybe tmobile isn't updated for iPhones yet. I don't know, please help!
