Hello.im new on the forum and I'm newbie with CDMA phones.so I have an iPhone 4s who was locked on Sprint.i made official unlock for the GSM modem but the problem is that many times have "no service" or one dot on signal display without work the calling.i inhabit in Europe so I don't need the CDMA modem.i have read if I delete the PRL file and some other files/folders from the phone it will work complete and first the GSM modem.as I have read now start the CDMA modem first and then the GSM modem.the phone is JB and iOS 8.1.2.
I tried many times to find the PRL file somewhere in the phone "wireless" folder but nothing.
Any help?
