I had an old BlackBerry that was from T-Mobile and I'm going to be using it on Cingular.

I recently got it unlocked <remotely no less! and for under $30 too!> and recently updated the software to Cingular's v4.0.2.xxx.

I'm currently getting a Data Connection Refused error, and I imagen that is due to something on Cingular's end <or the fact that I haven't gotten the BlackBerry package as of yet>

What I'm wondering is what, if anything, would be the difference of me getting the Cingular software package vs the T-Mobile package.

I have noticed the web browser is gone, but other than that, is there anything else that is majorly different that I should be aware of?

Thanks in advance!

Matt, if you haven't already, you need a blackberry data plan on Cingular. I've had both Cingular and T-Mobile. I actually prefer T-Mobile over Cingular because the unlimited days is truly unlimited with T-Mobile. I've noticed additional features that are on the later model bb devices with T-Mobile that's not on the Cingular bb devices. Yet, it is all a matter of preference from the users standpoint.

Certainly the APNs will have to be changed. Cingular tech support should be able to help.

The APNs will have to be changed?
Really...

You won't get anything until the data plan is provisioned for your account. Data connection refused is due to the lack of Blackberry data plan.

The software packages have pretty minimal differences. There may be fixes, themes, etc in one that aren't in the other.

The browser is gone because, once again, you don't have a Blackberry data plan. Once you're provisioned and the device is registered on the network the service books will be pushed to the Blackberry.

Before I got a Berry with a phone, I was an AT&T Customer. I was given a T-Mobel Berry with a phone, and got the unlock code from T-Mobile (long since gone!), and put it onto my AT&T account. This was just before the AT&T/Cingular merger.

The Berry and phone worked fine, but after the merger service began to degrade. Finally, the service got really bad, and the berry went south, so I went and got a new 7100 and got my account moved from AT&T to Cingular (a 6 month ordeal I wouldn't wish on anyone!).

Anyway, I did this through an independant dealer who told me that the reason the phone service on my old Berry was so bad was because while AT&T used the same carrier frequency as T-Mobile, Cingular did not, and they were slowly dismantling that infrastructure.

Maybe he was giving me a line, but he had no reason to - I wasn't going to go to another store, and I had to get a new device.

So, for what it's worth.....

ATT Wireless in many areas still used the 1900 MHz band and all of the older model phones at T-Mobile didn't include the 850MHz band,except the v600, BB 7290, and there may have been a few others. Cingular wiped out the use of the 1900 MHz band after the merger which made many ATT Wireless customers phones not work properly. Therefore, those customers would have to switch to a Cingular phone and plan and this lose their cheaper plan with more minutes, etc. It is a business thing that helped Cingular but not the consumer. Many consumers didn't want to lose their plans;therefore, they bought import phones online or got other phones unlocked. Yes, many even switched to another carrier.
