hi i am Preparing website for this mobile device as well i need to check every time in my mobile is there any website they can provide mobile device for testing so i can check every thing is on computer bcoz if i do small changes i need to check every time in mobile .
google - mobile emulator, you will get what you need. android emulator, iphone emulator, android simulator, iphone simulator
you dont' have to, it will work online itself, just give the url to your app ( can host anywhere) and they will load it and show it to you exactly the way clients will see it.
for example i have to test website www.yahoo.com then how can i chek online ? for mobile version as well
