MiniBB is right. Get the cradle. I have one for each of my BlcakBerrys.
I hate that USB port for charging. It was never intended as a charging port or for that matter as a sync port. It was put there for Admintechs to do maintainence work. It is far to flimpsy ever to be used long term.
Charging was done via the cradle. Those two big gold connectors on the back of the phone are where BlackBerrys were intended to be charged.
Sync is done OTA on BES.
Whatever you do do not buy a cradle that incorporates a USB port. These are found on ebay and are the worst possible solution.
Thanks for the tip on the additional charger but at $70 for an 8830 the bigger questions are (a) will the charger work with the Storm and (b) given that the only charging option from a vehicle is the USB port is it even worth it to continue with BlackBerry? I'm on my THIRD 8830 in 1 YEAR!!
RIM obviously has a potential class action problem on their hands.
