I just moved from Tmobile to Cingular because Tmo has no coverage in NC and they actually recommend that I leave them as a carrier. So far Cingular has been fine but I can't get my 8700G to work for email (BIS) on Cingular.

The 8700v I tried from Cingular worked fine for email but I had my 8700G unlocked (I'd been with Tmo for 5 years) and it works perfectly for everything except Blackberry Interent Service which I need for my push email.

Cingular told me to call Tmo and get my code changed to Cingular (different from unlocking the phone). Tmo was very helpfula nd called RIM 2nd or 3rd level support to find out how to fix this problem. According to RIM, I need to pay RIM $75 to get my CID code switched to Cingular or I can get Cingular to do it mayber...does any of this make sense, has anyone found a way around this?...

that's a bullshit answer...TMO should do it for you, no problem..

actually Tmo would have done it but since I already switched - and took my number with me my account was cancelled so they said they couldn't do it...they were very helpful otherwise. Of course, how could I have known about this code before swiytching - both Tmo and Cingular had to go through 2-3 layers of support to even figure this out...

It's something most people don't realize but it's always best practice to have your BIS account deleted and your PIN released by your carrier when you leave them.

Yes. this is exactly what I found yesterday. After speaking with both Cingular and Tmo PDA support and spending a couple hours on hold while they each try to figure out what was wrong...

Cingular says that my BB is still registered to my Tmo BIS account and Tmo says that my BIS account should have been deleted when I cancelled my service.

That was last night at 10:30 PM EST. Tmo says that it may take up to 48 hours to release my BB from the the TMO BIS account and then I can set-up my email on Cingular.

This all made sense until this morning when I received a registration welcome email from Tmo congratulating me on signing up for a Tmo BIS email serivce...and the cyle starts all over again...

I am thinking about moving my 8700g to Cingular, I travel a lot to NC and since T-Mobile has removed roaming on Cingular in the Charlotte area I am finding myself without my Blackberry. What is the advised step in getting T-Mobile to release the PIN from the BIS account, I will be canceling my T-Mobile account, and adding a Blackberry plan to my Cingular plan (line already exists, so no porting will take place). Also, any other help in making this a smooth transition would be appreciated.

Thanks

The only mistake I made, and I believe it was mentioned in this thread by someone else, was that I ported my number to Cingular and didn't manually cancel my BIS on Tmobile first.

What I recommend for this operation is that you log in to Tmobile and cancel your BIS account then wait for that to go through the system. After that porting to Cingular should be fine. In my case it took about a week to get Tmobile to disconnect my BIS account from my BB even though they said that this was supposed to happen automatically when I cancelled my service. After a week or so it works fine.

I was able to get my device unlocked from T-Mobile today, and will be adding the BIS feature to my Cingular account tomorrow. Final few questions, will I need to do anything (settings wise) with my BB in order to get data over Cingular's network? Also, since I will no longer be able to log into MyT-Mobile how will I get OS updates for the phone?

Thanks again for the help

Assuming you signed up for the Cingular Blackberry data plan it should just work once the PIN is released..

Of course, now you are a Cingular customer and get updates from Cingular when they have them.. I installed updates from another carrier for the 8700 following the instructions in the themes section here.
