Here is the situation. A female friend of mine was concerned her boyfriend was seeing his ex-girlfriend again. This woman is not technical but she is smart and focused. She bought a spyware program and hacked his computer and ALSO his phone ! She showed me the msn chat messages she has captured. Also SMS messages between the boyfriend and his ex-girlfriend. Her suspicions were confirmed but that is not the point. The point is how did she hack his phone? And more importantly ... she has used my phone at times and I also never hid my password from her as she is a good friend. Or maybe WAS a good friend? How can I check if she has hacked my iPhone4 ??? Or should I just back everything up and do a restore?
