******I had no problems with my Captivate that I purchased July 2010 until I downloaded the new update FROYO 2.2.******
Here are my PROBLEMS[/u]:
1) I cannot send any MMS nor receive them.
a. if I send a pic it says "sending" and never sends.
b. if I receive a pic it says "downloading" and it never downloads.
2) Everytime I connect to my WIFI, 98% of the time it says "Unable to connect, data connectivity error".
3) Also, I used to be able to adjust my volume from Silent to Vibrate to loud, louder, etc. Now I cannot do that, either you set it to Silent and have your volume adjustment loud, etc or you can remove Silent and add Vibrate and have your volume adjustment loud.
******So I called AT&T and they couldn't do anything without having to do a Master Reset which I did not do. So in turn I called Samsung and they told me that they couldn't do anything with my phone that it would have to be AT&T to solve the matter. Samsung also said that even if I were to do a Master Reset that my phone would probably not fix my problems. I asked Samsung if I could unload FROYO 2.2 and go back to the old version and they said no.
I loved my phone prior to the Upgrade and now it aggravates me!!!

I would greatly APPRECIATE any HELP that you may have, please.******
