:^/ RandomWit revealed:;^) The cable worked great, thanks. I replaced the 1039 PRL with 1050. So far, Opera Mini has installed now, when it hadn't completed the connection tests while using 1039.
Under the ##DEBUG# tool, the EVDO settings are different, too. I used to get Channel Nuraber reported as 65535, but now it's 1175. Similarly, Rcve power is reported as 104 instead of 0.
:^( However, the Current IP is still reported as 0.0.0.0, and AN/AAA Auth state reports "authentication failed" when it used to say "not authenticated." So it seems that the hardware/software are working just fine, except for one tiny niggling detail.
Maybe my settings just need to be refreshed at Cricket. I'll try that when I pay the bill today....
