I just got an email from Josep about a new release of BerryTunes. Personally I have not had a chance to try it myself but it looks pretty cool. They have spiced things up by adding support to custom online radio stations. No word that I can find on exactly what format of custom radio station they are talking about but this may get one step closer to Podcasts on your BlackBerry.
The software now also supports streaming over WiFi and using Bluetooth. There also seems to be some confusion about what devices the streaming will work well on. Personally I do not think EDGE has the consistent bandwidth necessary for streaming audio but I have been wrong before. The software also works with the new OS 4.2 8130 which is refreshing.
You can pick up a free trial (limited to 3 days or 30 plays) or a full copy from the BerryReview store for $19.99. If you do end up trying it out let me know.
