My phone is a Samsung IP-830 is flashed over to cricket sevice how would i set up my internet connection through Cricket?|||well when you flash a phone you cant guarantee everything will work (i.e internet, pic mssg's, txt mssg's,) so if you want your internet to work you have to reflash your phone but do a "full" flash. Make sure you take it to someone who knows what theyre doing because if not they can really mess up your phone.
