I have a HP iPAQ rx5915 (WinMo 5, QVGA in landscape) and
pandora_1.1.10[1].cab works great on it.
At first, I tried the install procedure in the 1st post of this thread. The program would start, but hang at "connecting..". I removed it and installed the
pandora_1.1.10[1].cab and it now works very well. Thanks, thanks, thanks.
