For those of you that want Tethering/MMS/and Visual Voicemail. I added the IPCC to the first post that gives you all 3 working perfectly.
Running OS3.0, Jailbroken, 16GB White Iphone 3G, Logo is nothing more than the AT&T text between the bars and the wifi symbol. Nothing in Cydia to suggest that I have any other logo installed or something to remove. I have Winter board but no themes, I have SBSettings installed but deactivated all but the main toggles, no extras in the status bar. I had benM's tether hack and tried your first version and it didn't work. It installed 5.5(or so it said in the About page) but under Settings>General>Network> there was no Cellular Data options page. I do have the camera icon in MMS and it takes pics and wants to send but all I get is the red !. I've rebooted, Win Vista, running Itunes 9.0.1. I tried installing IPCC 5.1 and got the Celluar data page with settings from another forum but it still didn't work, nothing but red !. I just now tried the Stealth IPCC 6.0, and I get the Cellular Data page in Settings>General>Network and have the following settings for MMS
APN: wap.cingular
Username: (blank)
Password: (blank)
MMSC: mmsc.cingular.com
MMS Proxy 66.209.11.32
MMS Max Message Size: 614400
MMS UA Prof URL: (blank)
Still only get the red !
Oddly enough, while writing this post, I just now got a text message from ATT (a day late?) saying;
"AT&T Free Msg: Picture & video messaging (MMS) is now available for
iPhone. Txt, pic or video msgs you send/receive are included in your
msging plan and subject to the limits of your plan. To enable MMS,
connect iPhone to your computer and click "Check for Update" in
iTunes, then restart your iPhone."
I tried to send MMS after this message, using IPCC 6.0 and it didn't work
I did what the mssg said and of course it didn't do anything so I went and held Shift, then UPDATE and tried what I gather is the official IPCC 5.5 file from your OP and restarted the Iphone. When I do this, I lose the Cellular Data page again and still get the red ! when trying to send. What should I see between the bars and Wifi symbols? Why isn't the Cellular Data page showing up with 5.5? Do I have a bad Jail Break? I used RedSn0W .7 something right after it came out, shortly after the 3.0 OS came out.
I don't have BossPrefs installed, I do have Icy installed, but rarely ever use it. I also have Appulous from Hackulous installed and have installed hack App Store apps. I do have the 5 row Icon dock app installed. My winterboard settings are as follows,
No Docked Icon Lables
The Simpsons - Ha Ha (text message sound replacement)
Transparent Dock
Black navigation bars
All other options are not checked
I'm at a total loss at this point and if it wasn't for the fact that MMS isn't all THAT important to me, I'd be forced to restore and update to 3.1. As it stands now, unless there is something here thats obvious to someone else, I'll forget about MMS until the jailbreak for OS 3.1 and Windows is available.
so any suggestions?
