I have an app on my G1 called Mobile Grid Client and am thinking of buying a HTC Tattoo, unfortunately the app is not available on the Tattoo. I have put the app to SD card from the G1 via AppManager, so could i DL Astro for the Tattoo insert my G1 sd card and launch Mobile client from there. I really want that App otherwise i wont bother getting the Tatto if it cant be done.
