Does iHeartradio stop loading, or keeps stopping on you, or freezing up? If your memory is full DO NOT UNINSTALL! Your phone might force you to clear other apps before allowing you to reinstall, and that process is mostly unnecessary anyway. Simply go to your SETTINGS app, then go to APPS within SETTINGS, click the iHeartradio icon and clear the iHeartradio CACHE and FORCE STOP. You should not have to clear out your iHeartradio data unless this does not work. After CLEARING YOUR CACHE and FORCE STOPPING, then restart your phone. Open the app and sign back up. Your original data settings will still be there unless you have cleared out your data.
