Ok, I tried to use pois0n on my Iphone 4 verizon 4.2.8. After I installed it the loader icon would do anything when pushed. After more research and being told I could use it, I found out it didn't work. I did a restore and reset my phone. Now I have no service, no network or anything. I've tried to reset it all different ways to no avail. Can someone please help me? Thanks in advance!!!
