I'm on TMO and followed all of the directions on this thread to the letter, but still am having trouble. My latest error message is 720: A connection to the remote computer could not be established.

Has anyone had this error and worked around it? I was wondering if the fact that I upgraded to the O2 .64 OS makes any difference? Would I need to revert back to the original .42 OS that TMO ships the phone with? I've also modified the APN setting on the phone, setting it to wap.voicestream.com.

I'm using the *99# phone number, and have +cgdcont=1,"IP","wap.voicestream.com" as my extra initialization command. I am not using a username or password when I dial the connection. My phone shows up as "Standard Modem" on COM4, which returns the following when queried:

ATQ0V1E0 Success
AT+GMM BlackBerry IP Modem
AT+FCLASS=? COMMAND NOT SUPPORTED
AT#CLS=? COMMAND NOT SUPPORTED
AT+GCI? COMMAND NOT SUPPORTED
AT+GCI? COMMAND NOT SUPPORTED
ATI1 Research in Motion / BlackBerry IP Modem
ATI2 Research in Motion / BlackBerry IP Modem
ATI3 Research in Motion / BlackBerry IP Modem
ATI4 Research in Motion / BlackBerry IP Modem
ATI5 Research in Motion / BlackBerry IP Modem
ATI6 Research in Motion / BlackBerry IP Modem
ATI7 Research in Motion / BlackBerry IP Modem

However, this matches some of the strings that have been posted above so I don't see any problems here. I've tried connecting with my 802.11 radio turned on and with it turned off. I have Desktop Manager v. 4.2.0.10 open and it says connected. The "network" setting on my phone shows:

Data Services On
Network: T-Mobile
Network Selection Mode: Automatic

My service books are up to date. The only other thing I can think of is that I've installed Opera Mini, Google Maps, Spider Solitaire and am using the BB Dimension Today Plus theme.

I'm really at a loss, unless, like my email issue two days ago, this is a TMO network problem and I just have to wait for it to clear up.

Any help here would be much appreciated. If I missed providing any info that might help, please let me know. Thanks!
