Uh, I have AT&T and my MMS works fine. I sent and received at least 20 MMS messages today.
My settings are
MMSC: mmsc.cingular.com
Proxy: 066.209.011.032
Image Size: High
UserAgent: iPhone
Everything else is blank.
If you have this working I am curious as too how? I say this because I stopped by the corp store and there are NO settings to allow this under the the following:
3G iPhone data plan which includes txt message packages.
There is nothing in there for them to enable MMS. The only way this can be done is through using another plan setup for the iPhone 3G, 99.9% of us that have the iphone 3G have the exact same plan except for the obvious of minutes and data packages.
I went home and called and the girl put her supervisor on and he said the only way to do it is by changing the whole package of data and MMS and because of the IMEI number there system will not let it go through and some other reasons. I spent an hour on the phone and we tried everything possible and rebooting my phone and everything we could think of and it would not work.
I can only speak for myself and my iPhone which I used QuickPwn on last night.
I have googled and tried so many settings that at this point its just NOT worth it to me and even if it worked its 25cents a message.
Anyone else got any suggestions?
