if i get one of these new SPs, (Eris, droid, etc) can i get a secondary phone, like my old razor or something, turned on, with the same info programmed in, and have it ring and everything when the primary phone does? I ask because im not intersted in payin 600+ for a phone and then destroying it...which i do alot. id like to leave my badboy in my truck or on my toolbox at work, and be able to carry around my smaller secondary phone, and use the smartphoen when i need it. i know when i upgraded to my dare, when my old phone was on, it would still get calls and text etc. anyone know for sure?
