hey guys...you need to have the proper service books. i got my unlock got for my verizon bold 9930 from http://blackberryunlocking.us and after i unlocked it, i asked for help on getting the phone working properly on t-mobile. they were nice enough to provide me with the service books and instructions on how to add them to my phone. i have full browser, mms, app world, facebook and twitter working.
Flimflammy, I checked Crackberry, and I was wrong in the other thread. The VZW 9930 will work on T-Mobile's Edge network only. No 3G. Sorry about that.
Here's a link to the Crackberry thread.
@torchlover, to answer your question no you will not need to reconfigure your browser settings when you go abroad. Since the device already has the T-Mobile APN configured, your Data and MMS will work while you are abroad. Keep in mind there are also International roaming charges to be aware of that can be found here http://goo.gl/4pRt , and there is also an awesome blackberry International Roaming package that offers unlimited e-mail and IM while you are abroad!
If you already have your service books loaded from a previous blackberry or you loaded them yourself. Use these steps with your 9930 to get full data services and email.
1/ You need to have BIS on your line first
2/ Press ALT + CAP + H on your home screen, then enter the code that you find here: http://www.zibri.org/2009/08/hidden-things-are-usually-best.html (you won't see the code on the screen as you type, but just type it), this will give you access to the engineering screen.
3/ Go here: Radio Engineering Screens (Multi) - 3GPP Radio Engineering Screens - GCF
Change these settings: Enabled GCF NV Flag and Sim Electrical Test On (your device will reset)
4/ Then go here: Radio Engineering Screens (Multi) /3GPP Radio Engineering Screens /Utilities
a) Ping self: if it says sth like "ICMP ping received in 19ms" -> go to step 2;
if it says "can't open APN" -> go to your normal Advanced Option screen/TCP IP and check the box "APN Settings Enabled"
if it says "Blackberry tunnel cannot open" -> turn off and on your GSM network.
b) Change these settings: HRT Enabled and Tmod ECN Enabled
c) Click on PS Detach (nothing will happen), check Ping Self again it will say ICMP Failed
d) Click on PS Attach. You have to be patient here. Wait for the registration message from RIM and EDGE (not edge)
The 2 last steps are very important, if nothing happens after a few minutes, PS Detach and then PS Attach right away (you can skip the Ping Self step now), and then wait 3-5 mins. Do it again if nothing yet. I did mine 4-5 times before I received the message from RIM.
After you see EDGE and a message from RIM, go to Host Routing Table and Register Now.
