After writing the article on how to listen to Podcasts on your BlackBerry I had Robin of PodNova bring to my attention that I had missed another free desktop client. The Podcast website PodNova.com has a Podcast client for all 3 major OS’s.
As Luc brought up in a comment on the above mentioned post there is no Juice desktop client for Linux. Juice has promised support for quite awhile now but PodNova beat it to the punch. The PodNova client supports Windows (2000, XP, Vista), Mac OSX 10.3 or higher, and Linux (w/ Python 2.5). You can download a copy for your OS at this link.
I have not had a chance to check it out throughly myself but PodNova is pretty reputable so I would check it out if Juice is not working or you just hate iTunes .
