I know there have been so many posts over the years about these sidecars, but it seems like the issues with them never end. I have a lot of customer's who have never complained about them, but for some reason there are a good many that always have to unplug the phone for 15 seconds to get them to work again (every few weeks or so). The software release of the IPOs range from 7.0.32 - R9.0.2. Does anyone have a good explanation for this? Maybe it's environmental somehow?
