hi, how can i roll back the settings after upgrade done or how can i switch to GSM after updating to LTE?,
im using iphone 5, once upgrade my network settings to LTE. everytime I turn of LTE, IT Automatically turn on to 3G, but my location has a poor signal for LTE and 3G, so i want to switch to GSM GPRS only. atleast i will have stable signal for messenger.
