Please bear with me as I am a recent convert to Android having been with Nokia and their Symbian system for years It's soooo outdated compared to Android I have been trying to install both the Swype beta apk & the HTC keyboard apk files onto my X10 for the last couple of days. I followed the instructions to get the file on my SD card and when I go to try and install it (using Astro) the phone keeps on asking me if I want to install it . I have the option in 'Unknown Sources' ticked to allow installs NOT from the market. I was going to format the SD card to see if that helps but I don't know if that will lose any system files vital to the phone... Strange thing is that the ADW Launcher installed fine and I didn't get that from the market.
