The answer is, it depends. If you already downloaded and installed the Thwapr app, then you are all set.

If you have not downloaded the app, then we'd suggest you accept their invitation.

As an iPhone user, if you are invited to join, you can download the Thwapr iPhone app and have a great experience.

You can also join Thwapr as a mobile web user - on the iPhone or on hundreds of compatible mobile phones.

An alternative to joining Thwapr, you can simply receive videos and photos on your phone shared to you by friends and family or brands/content owners.
