I've read all the messages I can find, so I am sorry if this has been posted. I am atempting to get

Account: T-Mobile / BB Unlimited
Device: Blackberry 8700c (unlocked)
PC: Dell Laptop

Working as a modem. I've seen lots of 7xxx devices get working with T-Mobile but have yet to see or read anything about a 8700.

It all seems to come done to the init string that the blackberry does not respond to:

AT+cgdcont=1,"IP","wap.voicestream.com","",0,0

Anyone have any luck?

The Solution to this problem is simple. This guide gets the credit for the fix

http://home.comcast.net/~tamsterra/Blackberry_8700c_Model_Tips.pdf

The correct init String is
+cgdcont=1,"IP","wap.voicestream.com"

I did not use a user ID or Password.

The full how-to on making this work is located here: (but you need the above string so put it in your paste buffer) ==>
