I have this phone and install apps almost everyday. I have to say that TuneIn is good, but local stations like DC 101 have only approved licensing for IheartRadio.
When I try to run the app on this phone, it does not work well, slows it down so bad that either it force closes it, or I have to close it so i can go back to normal operation. It completely hogs the memory and prevents you from multitasking, that's how bad it slows the thing down.
Even though I run all apps from my 16gb class 10 sdhc memory card, I have only 40 megs of phone memory available after installing all the apps I need on a daily basis. I have at least 10 custom apps installed.
I run an app killer that works quite well, but apparently that isn't enough to run iheartradio in a efficient performance manner.
I have a yahoo question open on the issue, so far no responses.
