Android Text Messaging Application

I need an application that will run on android 2+ that will do 3 things: 1. Have a URL to post incoming text messages. All text messages received will be posted to this URL in this format: [login to view URL] is a test message&timestamp=2012-10-03 13:03:47 2. Receive a URL post at the phones IP address (wifi) that will send a text message, this will look like this: http://phoneip/?sendto=5551234567&message=This is the message to send 3. Check a website at a set number of seconds (variable) and download an XML file, and when it gets this file it will send all of the text messages in the file, in this format: < messages > < message > < to >5551234567 < / to > < text >This is test text < / text > < / message > < message > < to >5551234567 < / to > < text >This is test text < / text > < / message > < / messages >
