How many can be used at once?

[Shannon]

You should never use more than two programs at once if both of them are 4G. 4G is too intense by itself, even a Type B.

You should never use more than one program that has a Type C or D component to it at a time.

Any program that does not have its type specified in the title in the store will be 3G, and can be determined for type according to its goal.

4G titles always have their type listed in the title of the product description in the store.
