"Disconnection Problems with iPhone 4 Locks-up Device"2.0 starson by AiryDisk
Pros: Perfect fit, loud audio volume, iPhone battery meter, Stealth mode, build quality, fast connection time, styling.
Cons: Buggy firmware causes device to lock-up after power-down with switch. iPhone thinks its still connected and it takes either a charger connection or several hours to reset where it will power-up and connect.
Summary: I really wanted this to be the successor to my HX1 but the firmware issue is a deal breaker. I've tried several units and they all do the same. Many others are reporting this in various forums. I hope Motorola realizes this problem (I've called to report it) and fixes it. I'll buy another after its fixed.
