I have a BB 7290 and I have the Cingular Blackberry plan. When I turn the unit on, and turn on wireless, and it searches for network and initially says GSM and after a moment, it switches to gprs. Uggh.
I used to run a OS that was 4.1.5 and it used to stay GSM but I didn't have the blackberry plan on my account then. I tried changing the TCP settings:
APN: wap.cingular
Username:
![[email address]](?emailimage=926ba5063332a843f899526b95997cb8)
Password: Cingular1
This is also to no avail.
I have also registered the phone with the PIN and IEM on the blackberrystart part of cingular's website.
I have yet to access the internet with this device since it was given to me. My questions are;
1) Could an older sim card be a possible origination of discord?
2) I have tried resending the Service books to myself many times but the unit doesn't stay connected long enough when it first turns on to receive them.
3) Being that I am running the BB 4.1.3 on this model, could that be the source of error?
4) Could it be on their part?
Any help WHATSOEVER is greatly appreciated
