UK based Omnifone and Research in Motion have announced a deal that will bring unlimited music downloads to Vodafone BlackBerry users in the UK via MusicStation, Omnifone’s mobile music download service.

MusicStation will set you back about 2 pounds, or, $4 per week and will allow you to download as many of the over one million available tunes that you like. This could be significantly less expensive then the per download cost of iTunes if you download over 4 songs per week. I wonder, however, if you could still listen do your downloaded music if you let your subscription to MusicStation lapse.
