I want to know if I can use an adapter to connect an airecard to my itouch.:)

The problem with that is an air card uses electricity to run and I am not sure if a itouch can convert with its USB port for electrical usages. Take it to an apple store or call their toll free number. A person who deals directly with an itouch on a day to day basis for accessory purposes would know a great deal more about this product.

Another member gave a link about this when the question was asked once before. See if it's helpful.
