I have been reading all kinds of forums to figure out these mms settings for my blackjack i617. I need to know how and what settings to put, step by step instructions. Thank you for your time.
With the phone unlocked and the Windows Mobile upgrade already completed, the phone will boot up and make and receive calls. Data connections are not possible, because the AT&T service configuration is still in place. Next, we will enable data connections for T-Mobile.
GPRS Settings
On the phone, go to Start/All Programs/Settings/Connections. Three connections will show up with a lock symbol next to them. They can’t be changed or removed from here, but that’s fine since we can add new ones. Add these two (select Menu/Add):
Description
t-mobile internet
Connects to
The Internet
Access point
internet2.voicestream.com
leave the defaults for the remaining fields
and
Description
t-mobile mms
Connects to
WAP network
Access point
wap.voicestream.com
leave the defaults for the remaining fields
Proxy Settings
In the Connections menu, right after GPRS there is an entry for proxy settings. Select Proxy and you will see the AT&T proxy definition, also locked. Let’s add the T-Mobile proxy settings (select Menu/Add):
Description
t-mobile proxy
Connects from
WAP network
Connects to
The Internet
Proxy
216.155.165.50:8080
leave the defaults for the remaining fields
Now you should be able to browse the Internet. What I don’t remember is if I had to select the T-Mobile connections somewhere (I think not), or if they got selected automatically. This could be a step that is missing here.
MMS Profile
Next let’s fix the MMS (multimedia messaging) settings. Go to Start/App Programs/Messaging/Messages. Select Menu/Multimedia Msg. Options (scroll down to see this option)/Multimedia Msg. Profiles. Delete the AT&T profile that is there and create a new one with the following settings:
Profile Name
t-mobile mms
MMSC URL
http://216.155.174.84/servlets/mms
Proxy
check
Address
216.155.165.50
Port
8080
GPRS
t-mobile mms
leave the defaults for the remaining fields
Now you are able to send and receive multimedia messages.
Go to Settings - Connections (6) - Wireless Manager (1)
With Wireless Manager highlighted (do not press the OK on joystick), select Menu then Advanced.
Internet connection - Select TMobile or whatever you named your GPRS for connecting to the Internet.
Select Done and exit out of there.
You should now be on the internet when you go to the Explorer.
ICS (Internet Connection Sharing) Hack: Enable Tethering via Internet Sharing using the MEdiaNet connection
HKLM\Comm\InternetSharing\Settings
In here will be a value named "ForceCellConnection"
Change "ATT ICS" to "" and reboot.
ICS will now allow you to choose either ATT ICS or MEdia. ATT ICS will not work without a tethering plan on your wireless account, but MEdia Net will work as long as you have the signal and the basic pay-as-you-go feature (not recommended).
ATT ICS uses "isp.cingular" (tethering) whereas MEdia Net uses "wap.cingular" (general internet).
Unlocking ICS and Media Net
The ATT ICS and MEdia Net entries in the connection settings dialog are read only and won't let you edit them, But if you navigate to:
HKLM\Comm\ConnMgr\Providers\{7C4B7A38-5FF7-4...}\Connections
There will be 2 keys in there. one for ATT ICS and MEdia Net. In those keys there will be a value of ReadOnly. Change the value for these from 1 to 0 and reboot your phone. These connections should now be editable.
