I have made some modifications to MobileWish client , with some fixes and feature, which will be released soon . The new changes include:
A Calendar: that will show you the latest events that are coming so that you can send cards
Specially For You: This will be a content channel, where some goodies can be browsed (even download if permitted) by the user. These may include Flash Lite wallpapers, applications & games (specially designed to run with out the softkeys), mini ebooks and elearnings etc.
The desktop version will also be a little better in looks and a same type will be available at the MobileWish site header, so that you can also login from there.
And yes there will be more cards too.
