As i can see, reading all few forums
, there was no attempts.
However, I believe, the future is with stopping of IREX dealing with Verizon only. DR800sg's module supports much wider spectrum of operators and protocols. It will be stupid marketing in front of every major electronic company working under its own digital reader. Hope, they will think about it and unhook DR800SG from exclusive Verizon support. And, think, DR has SIM-card slot, but Verizon does NOT need SIM-card(!!!), since it's 3G already. So, what's for SIM-card slot presented here?! May be, for future developments...
