I haven't found much info for this model anywhere. I got this in the mail yesterday. I discovered I had to modify the SIM. No biggie. I also found out that on the Android 4.0 platform that the APN app no longer works. Legality issues being passed the Jan 26th law? I don't know. Having the AT&T model with the Straight Talk SIM I noticed that I can make calls, text, (awaiting mms) had poor signal last night.
1. How can I tell if I'm on a LTE or 4G network?
2. If not, will I have to root or flash anything, if this mod is available.
I understand the 21 vs 42 a little bit. Any information is helpful. Thank You for your time & posts. Greg..
