I had like 100 apps on my phone so i didnt want to take the time to delete all of them, so i set it to factory setting and now it says i have to activate it again, can someone plzzzzzzzzzz help me. will this cost anything?
Factory reset clears your phone of everything. If you have photos, music, etc. on your SD card, those should be fine. And, no, it doesn't cost anything to reactivate your phone.
