I was just reviewing some of the posts in forum to see if I can find a similar case as I have with my iPhone, but I couldn't find an exact same thing so I'm asking for help in here.
My iPhone came with 1.1.2 and bootloader 4.6. I used ZiPhone 2.4 to unlock it. It went ok with no error. But I have some issues:
1- I cannot make calls using touch pad (closes down after i tap on any number) only contact list entries can be dialed.
2- I cannot read/view SMS (closes down and goes back to HOME page when I tap on SMS icon)
3- When calling or receiving SMS, I do not get any ringtone, or SMS alert. The screen only turns on and WORKING icon appears, but no ANSWER/REJECT button or anything.
4- I cannot view my recent calls section as well (no missed calls).
5- I can work with one of my SIM cards but with another one it does not detect network. ( I have not run AnySIM. will that solve the problem?)

By the way, I have reset network and all the phone settings but no change.
You Tube, WiFi, Safari, Weather, Maps they all work fine.

I have been recommended to upgrade to 1.1.3. I don't have any problem with leaving 1.1.2 but I want to make sure if restoring to 1.1.3 (and using ZiPhone to unlock it) will solve the problem for sure. Any comments/ experience?
