Do you have no access to a wifi broadband router (at home, or office, perhaps) ?
I just checked with my Galaxy Ace and the 'Tune In' radio app, and can get LBC (97.3) on that (there's also the LBC News {on AM 1152})...
I have TuneIn Radio Pro (purchased) but there's also a freebie version (which should be still easily available - I bought the other version about a year ago but don't know current price).
If you have Wi-Fi you could probably listen to LBC without worrying too much about how much data it uses, and not even need to download a podcast from anywhere... Incidentally, not sure if LBC does podcasts of much (or what else might you listen to?)
Do try TuneIn Radio, it has hundreds of stations, from locations worldwide (and if you are interested, I can recommend various alternative services like World Radio Network (WRN English for Europe, or WRN English North America for similar but not identical content)... nearly all talk, English from around the world...
Also from N America, NPR {National Public Radio} and PRI {Public Radio International} provide lots of shows for the public radio stations. I can recommend shows like "Fresh Air" (daily current affairs and interviews), Wait Wait, Don't Tell Me! (a weekly news quiz, with special guests and US comedians... just a bit of fun!). Lots more and many may be available via TuneIn as it seems to be able to find both live stations and links to podcasts/ audio clips... for example I'm just listening to a bit of Fresh Air about actor James Gandolfini (from The Sopranos).
