posted this on pinstack some time ago... give it a whirl:
this applies to the 188.8.131.52 for 8700 mentioned below, and all os 4.5 that i have tried on my 8320.
howdy folks... i got a tomtom one not too long ago and ive been scratching some anatomy trying to figure out how to get the darn thing to connect to my tmo 8700g for data services.
i just put the 184.108.40.206 on it and its working great... im using the berry to get wireless through my bluetoothed mac laptop, and i wanted to take advantage of the PLUS services of the tomtom one.
after playing around for hours with the berry and the tomtom, here are the settings they need for data to work (weather, traffic, traffic cameras, instant messaging, buddy location, etc.):
options --> advanced --> TCP --> apn to wap.voicestream.com (we already knew this, right?) no username or pee-dub.
on tomtom one:
Connection string: AT+CGDCONT=1,"IP","wap.voicestream.com" (case and whitespace sensitive)
for the tomtom, do a manual setup... disregard the 4 tmo options and use auto ip and dns settings.
goodluck, and be amazed! whoa!
