One of the nice things about T-Mobile’s GPRS/EDGE data service compared to others (such as Verizon Wireless) is that it lets you use your phone as a wireless modem. And, it worked fine until this past April. Up until this past April, I used internet2.voicestream.com (NAT) Access Point Name (APN). It stopped working at that time and I switched to internet3.voicestream.com (public IP). However, when using my phone as a wireless modem using a Bluetooth connection to my Pocket PC with a nice big QWERTY keyboard, I had to drop the connection from 115.2Kbps to 38.4Kbps. I had to use my phone as a wireless modem a bit over the past week. I played with the settings and verified that I was limited to 38.4Kbps. Then, I switched the APN back to internet3.voicestream.com. And, yep, I was able to set the Bluetooth serial connection speed back up to 115.2Kbps.
