Help please!! We are Apple users, have an IMAC, Mac book, IPad, etc... We also purchased approx. 2 wks ago 2 IPhones 4G....my husband is not crazy about the service, dropped calls which we never encountered with Verizon... to make matters worse we were at the mall yesterday and he fell in love with the Epic 4G...question is now do we dump AT&T and go with Sprint? Is Sprint the only carrier that provides service? We are south of Tampa FL and the Sprint map showed Good-Fair voice service..which is a concern since this is the reason we are ready to dump our IPhones. Also, can the Epic sync and play nice with our other Apple equipment? If anyone has any advice I would appreciate it!! Thanks in advance.
