Online storage is getting more viable these days, especially with bandwidth on the rise and costs falling. What better way to join in the fun then accessing it on your trusty iPhone? Box.net, a CNET Webware 100 winner, is now offering online storage access for the iPhone, enabling users to store and view Word, Excel or PDF documents.
I’m not sure whether you’ll be thrilled at the data speeds over AT&T’s EDGE network, but it’s surely a nice service to have. Users can get the first gigabyte free, but you’ll have to pay for more. Box.net also offers solutions for businesses and enterprises that include features such as collaboration and integration.
