Q: how to fix my iphone 4 keep searching

Aug 8, 2013 12:06 PMby NRJGadget Repairs,You can diagnose it step by step.
1). Try is with the different sim (if its unlocked if not may be same network but differnt sim)
2). Try resetting the phone by putting it in dfu mode and restore it from scratch.
3). If its still doing that and cant find network then It may be antenna which needs replacing.
Hope this helps.
