My 5th wp7 app just went live 🙂
Its purpose: sending a text message from your browser!
Download the application from the WP marketplace, login, take another device (desktop, laptop, tablet, another phone, …) and browse to http://mendel.somee.com (my current free asp host 🙂 ), login with the same credentials as before, type your message, send it to your phone, and send it again! 🙂
This makes you can write an entire book-long message, on another device (maybe even with physical keyboard 🙂 )
