Has anyone had any luck doing this with Sprint? I have an 8703e but have run into two problems:

1) With DUN it tells me that it's failing to connect.

2) With PAN it attempts to connect, and either tells me it can't see the phone, at which point I remove the connection and re-pair it, or the device resets itself as the "Bluetooth PAN connected" message comes up.

I'm currently using an N810, and was wondering if anyone else had experienced the same trouble.

Thanks,
Jeff

Hi guys below are instructions for conneting to tmobile internet with the MDA but the process should be the same with all tmobile phones. Im posting this because I noticed a lot of people are skipping the easiest method of just putting in the username and 4digit password in the connectivit option screen

I have the N810 and the tmobile MDA. I finally got the two to pair and connect to the Tmobile internet. It took about 2 days to figure out but I guess it was worth it. You definitely don't have to do all of the things that Dan listed. Once paired its just a matter of updating the "Tmobile Internet" with the proper username and 4 digit number password that was given at the time of pairing. I will try to explain below the process of getting it paired and connected because for some reason it didn't pair the normal way for the MDA. Please note if you already have your devices paired but just can connect and you know your 4 digit pairing passcode you can jump to the middle of my post which will tell you how to get the device connect to the tmobil internet.

DO NOT pair using the phone option under settings, for some reason the MDA will pick up the N810 but the N810 wont pick up the MDA for pairing when done under the phone option.

-From the settings click on the bluetooth option.
-Once there make sure the N810 bluetooth is on and visible and then click "devices", if it already has pocket PC there just delete it and then select new.
-Make sure your bluetooth from the MDA is turned on before you click new. Once you click new "pocket_PC" will appear right away. Wait for it to finish search and then select the "Pocket-PC" by clicking it twice.
-It will then give you the 4 digit passcode for pairing. At that point your MDA will ask you if you wish to grant access to the N810 and once you click yes the MDA will ask for the passcode. Enter the 4digit passcode from the N810 and click next on the MDA. Once that happens the devices will pair and the N810 will say "devices paired" after about 10 seconds (also write down the passcode so you dont forget it)._

Setting up proper T-mobile connection

Close all the windows by clicking close one screen and ok on the other. At that point your pairing process has been completed. The next step is setting up the connection because if you try to just connect without going into the settings it will just search forever or say connection failed. It does not officially connect to the MDA internet unless it says that and it usually takes about 10 seconds for the N810 to tell you.

-Click the connection signal at the top of your N810 and the click "connectivity settings"
-Click "connections" and then click the "T-Mobile Internet" and click edit.
The "GPRS" box should be selected and then click next.
-You will now see the connection setup:GPRS screen which is how you will get the N810 to connect via tmobile internet.
-The "Access point name may read "internet2.voicestream.com" if it does YOU MUST change it to wap.voicestream.com
-the dial up number remains the same which is "*99#"
-The username is "nokia" and you must type that in
-The password is the 4 digit password that you were given on the N810 at the time of pairing the two devices so please enter that in the password field
_Click next and you should get a message advising connection is complete and you can click finish.

Now you are ready to connect by click the signal icon and clicking "select connection".
-Click the "Tmobile Internet" and click connect. It will take about 10 secs and then you are ready to browse.
It does run a little slow but its definitely tolerable. Any questions feel free to email me.

Finally got this to work with AT&T myself after numerous attempts.

Upgrade the blackberry to OS 4.5.0.52 (do a google search on the web). Delete the bluetooth connection on both the N800 and the blackberry 8700. Re-pair the 2 devices and it just works. It even creates the profile for you and everything.

Thank you! I finally got my TMO Curve to work. This method removed all the unnecessary commands and simply worked. I am using OS 4.5.0.69 for the curve, however which is a beta and is incompatible with bluetooth while wifi is on. Otherwise it works like a charm!
