I know this is more of a T-Mobile problem probably but has anyone had any trouble downloading apps on cellular? For awhile now, going back to the iPhone 5 probably I've never had any sort of consistency downloading apps on cellular. I usually have to wait until I get home and do it on WiFi. This is most painful when doing a restore. I get the "Unable to download, please try again later". If I'm extremely persistent I can usually get them downloaded after a few dozen errors or so. Anyone else? Any suggestions?
