my iPhone 4s won't turn on unless plug into wall charger, but after I did that my phone showed some things wrong like the clock changed to 7AM, no network service (keeping searching), wifi disabled (can't click), then a minute later it went freeze.

Basic troubleshooting steps outlined in the User Guide are restart, reset, restore from backup and restore as new. Try these in succession until your problem is solved. If your problem does NOT get solved, then you'll need to bring your phone into Apple for evaluation.

Hi, I just had the same problem with mine. It would only turn on when plugged into wall charger but would not stay on for long when plugged in. It also said I needed to restore and I had no wifi or cell service. I took to Verizon and they said I needed to restore but i would loose all saved data. I did not want to loose all pics and contacts so I took to a place that repairs Iphones in my city. They took one look and said had a bad charging port. They said they could replace it so that I could then back up all data on my computer before I had to restore. Suprisingly to them, once they replaced the port and put a new battery in, it all worked fine again; even wifi and cell service. The fix cost about $60.00 and I did not loose any data! I have ever posted to any online forums before but had to on this because I want people to know that they don't always have to loose all data!!!
