Is there autocompression on the Cingular network...
My questions are: When using MMS as the medium why does the system shrink jpgs, mp3s, and gifs prior to delivering them to the phone from an email? All image files I tried were edited/cropped so that they would fit on the screen of the v600 prior to sending, but after sending them the system shrinks them before delivery. All mp3s were less than 30 seconds long and compressed at 64 kbps, but when they arrive in the phone they are 8 kbps. Is there a way around this?
You just beat me to post the same exact question! I thought it was just my phone that shrunk it but now I see that it is Cingular MMS servers doing it! The most logical answer is that by shrinking them it makes it smaller size to send. The other way is to set-up a mywirelesswindow account, then use that as your pop3 email account and just download to your v600. When sent through standard email instead of the MMS servers the pictures come in their original size.
I am not really big on MMS or SMS use, but 200 and 1500 of these are available to me along with my MEdia Works. I have so many of them available that I was trying to find a use for them. I have noticed that this compression is not just with messages via the MMS servers. I also noticed that while my phone is tethered to my laptop IE6 displays "dummied down" images when browsing the net. In this respect this is actually a good thing as far a rendering a page goes, but I sure wish they had given us some control (on/off) over the compression.
i connect to the internet using cingular's data connect kit on my laptop and there is an option to turn off that compression...so it displays the webpages how they SHOULD be seen instead of crappy pics...

I was just wondering whether Cingular did compression on tethered connections. VZW does not (doesn't even offer it) but Sprint PCS forces it on its users. A couple months ago I started up a proxy server for PCS Vision users to be able to bypass it while tethered.
cingular does not...i use cingular's QuickLink data connect kit and it's in the program's settings...it has nothing to do with the phone...i just suggest you guys buy the data connect kits?

Apparently, at least in my area images are compressed, as they were on SPCS, using the isp.cingular APN by default. If the DC software can turn that off, there ought to be a way to do that without the software as well... To be honest, it doesn't really bother me, except when I'm trying to view radar images and it does a poor job dithering.
I wonder if Cingular's proxy respects the Cache-control: no-transform header...

Check out my Vision proxy at http://www.stevecrow.net:8080/ to get an idea how it works. Then fetch your IP address while you're dialed up to the Cingular connection (if you want an easy way to look it up, try http://www.stevecrow.net/~scrow/ip.php ). PM that IP to me so I can examine the domain name and stuff, and I'll open up the proxy to Cingular users and you can take it for a spin to see if that helps. Gosh that was a long sentence.

I can answer THIS one: are you logging in (with *whatever* software) as WIXDC001@W5.MYCINGULAR.COM .. and/or with an APN of ISP.CINGULAR? If so, change it

According to the DC info Cingular has on their developer's site, the WIXDC001@whatever logins are deprecated. For GPRS you should be using ISPDA@CINGULARGPRS.COM/CINGULAR1 to get DC with compression.
