I don't know if Sprint is up to something, or I borked up my phone, but as of the last 2 days or so it won't connect to existing 3G service on my SGS3 if the radio is set to LTE/CDMA but just fine if it is set to CDMA only. In some places no problem but in others I have this issue. I've noticed it at Newark Penn Station too. -- * seek help if having trouble coping --Standard disclaimers apply.--
