Hi, my daughter just gave me an att iphone 4. I have verizon. I just wondering, is there anyway i can unlock the iphone 4 and bring it to verizon to get a microsim and use it? or verizon doesn't support unlock att iphone 4. thanks
No that could never happen.
Read up on the difference between gsm and CDMA technology.
If you unlock it you can use it on any gsm carrier like Tmobile, straight talk, simple mobile, h2o etc.
Never on verizon or sprint.
