Okay, the only other option
is to do a DFU Restore of your iPhone. Sounds like you have a corrpution in your iPhone firmware. The DFU restore will wipe the iPhone completely and you will need to start from scratch.How to Perform a DFU restore (which is significantly different from a standard restore):
First, remove your SIM card. Then, with your iPhone is plugged in to your PC, hold the Home
until your iPhone powers down, continue holding Home
for a full 4 seconds.
If you are having trouble with this, please refer to the video below for assistance.http://www.youtube.com/watch?v=ofpinyGlQ8I
Release the Power
while still holding the Home
key until iTunes tells you the iPhone is in recovery (your iPhone screen will be black, but it is on) and then doing the restore to latest firmware.
After the restore, when prompted, do not
select Restore from Backup
. Select Setup Up A New iPhone
After the restore, see if you can send a MMS and receive one.
If you can, from there, you will need to resync all your apps/music to your iPhone.
If you cannot, you have hardware failure and you will need to take your iPhone to the nearest Apple Store Genius Bar
) to get it repaired/replaced.
There is no software fix or key sequence to fix a hardware issue.
