Basically I am unable to log into LTE after using the Phone Info app to force a 3g connection. On ICS I was able to switch back between LTE and 3G without a problem. With JB the phone is stuck on 3G and won't go back to LTE. I did a 'google search' and found others with the same issue here: Stuck on 3G after Jelly Bean upgrade! - Android Forums at AndroidCentral.com One fix (for other versions of the S3) seems to be going into settings/more settings/mobile networks/ and choosing LTE directly from there. Unfortunately this option is not available on the Metro version of the S3. So what are my options? Is a factory reset the only way?
