The new 1.74 firmware will recognize my Huawei e160 USB 3g Tmobile sim. If I select add 3g network and enter a name - tmobile - or anything else and leave other fields blank it will connect to the net. But I only get Tmobile's web2go page and not the full net as there is no way I can see to tell the M003 that I want the internet2.voicestream.com apn and the appropriate proxy. I tried using the apn on/off app but when I enter all the new apn info it won't save it.Ideas on how to enetr this APN info? I can't get the dialer app to open either. But the M003 IS connecting to the net with this Huawei usb sim attached. It is very fast when surfing the basic Tmobil web my account pages.Any help would be appreciated as I would really like to get this thing surfing with 3g in addition to wifi. And yes, I do have an unlimited data subscription on this sim.
