I've got an unlocked pearl that I'm using on Cingular without any problems outside of the MMS not working. Through the diligent research of an extremely helpful Cingular store rep, I've got a fix. But it only works if you're using it with BIS. More on BES below.
Under Options, then Advanced Options, then TCP (its the last option at the bottom).
Set APN to:
wap.cingular
Set Username for APN to:
Password for APN is:
CINGULAR1
Those settings are case sensitive so pay attention to that.
Unfortunately, I am on BES through Mailstreet and once I layer the BES Enterprise Activation on top of the Cingular Service Books, it stops working. Cannot get it figured out at all. Have talked to Cingular and Mailstreet and neither is helping very much. If anyone has any insight as to what Mailstreet BES service book might be causing the problem, I would greatly appreciate it.
These are my service books when the MMS is working and prior to BES from Mailstreet:
IPPP for BIBS [IPPP]
Blackberry Internet Browsing Service
MMS Client [MMS]
MMS Transport [WPTCP]
WAP2 Transport [WPTCP]
WAP2 BrowserConfig [BrowserConfig]
Cingular Browser [BrowserConfig]
Cingular WAP Secure Transport [WAP]
BBFS1 [BBIMConfig]
Wap Push Config [WAPPushConfig]
IPPP for 5 Click [IPPP]
Browser Config for 5 Click [Browser
Provisioning [PROVISIONING]
After Enterprise Activation, it adds the standard 6 service books:
Desktop [BrowserConfig]
Desktop [SYNC]
Desktop [CICAL]
Desktop [IPPP]
Desktop [ALP]
Desktop [CMIME]
I was getting the Red X same as everyone else. During one of the troubleshoots, I systematically deleted each of the BES service books and tried the MMS. I deleted the Desktop [CMIME], then Desktop [BrowserConfig]. Nothing changed, still Red X.
Then deleted Desktop [IPPP]. At this point, no more Red X but it still would not send out the MMS. It would give me the circle and just hang there like it was trying to send it out. I considered this improvement and leads me to believe the IPPP is the culprit. But I don't think I can just delete it.
If anyone has a better understanding of how all these things work together and can think of anything, let me know.
