I searched around to see if this was an issue for anyone else, but it doesn't appear to be. I downloaded and installed PdaNet right after I bought my phone about four months ago (Sprint Hero with stock ROM), but now a search for "pdanet" in the market yields no results. Could this possibly be because I'm running 1.5? Does anyone else who has a Sprint Hero have this problem? The only reason I'm wondering is because I'd like to get the newest version to use it on my Mac so I don't have to open VMWare Fusion each time I run it (and hopefully get bluetooth access when we get 2.1).
