I moved my Unlocked 8700c to T-Mobile today, and the transition was seamless. At the moment though, my BIS is still associated with the Cingular login, and not yet available from T-Mobile's link. Fortunately, my e-mail accounts are working, but the sooner it's canceled via Cingular, the sooner it can be properly provisioned by T-Mobile. Anyone have any idea how long this typically takes? Thanks!

don't see why it wouldn't be instant - i'd call Cingular and have them cancel it w/ you on the phone

That would be my expectation too, but they didn't do as I requested yesterday when I asked/canceled that phone, and of course, Cingular is *closed* on Sundays. I did call an after-hours line, got a very nice rep, but the "data services group" is, well, closed on Sundays. So, it'll be another call (the third), and more on-hold time tomorrow to get this accomplished. I called the T-Mo folks, to see if they can help push this from their end as well.

it will make sense if you tell them to release your PIN from blackberry.net which means they need to contact RIM for this.. otherwise it will be a problem n they will keep telling that it is done but in the back end @ RIM it is not DONE.. I had the issue. ... so to let you know.

Thanks. That's pretty much the terminology I plan to use when I call them. I confirmed that they *did* cancel my phone from the account, so I'm sure the BIS account will be killed soon anyway. But, rather than be killed/deactivated, I'd prefer they released my PIN, as I had asked.

I took an unlocked TMobile 8700G to Cingular. I called up Cingular and they did all of the work to have it moved over. There was no need to have TMobile do anything (just as long as it was unlocked) as per the Cingular rep.

Exactly my understanding as well. I believe Cingular's Data Support group starts their day at 8:00 AM, so I'll be calling them soon.

Yes. It took 5 minutes, and the BIS was instantly available/configurable from the T-Mobile side. Excellent! Just a matter of getting the right person, to do the right job.

Glad to hear it worked out for you!

Thanks! I realize that as with everything else, "your mileage may vary", but overall, I have to say that T-Mobile has been absolutely outstanding to deal with, and I have no regrets moving over from Cingular. From the in-store associates to their 24/7 call center reps, they've been nothing but 100% professional and courteous. At one point, I was on hold for no more than 3 minutes, and I was asked, "Are you ok? I'm still doing some checking here". Amazing. Of course, after I got the right person, Cingular also took care of my request, but that was 2 days after my initial request. All things considered: price, signal in my area, call quality (no latency/echo, etc), and customer support, I've become a T-Mo "fanboy".
