As Google Android is open source a user doesn’t have the stick to the Android Market to get their applications as there are other sources around and will probably be even more Android app sources given time.
One site to enter the Android app business is Phoload, who not only offer plenty of applications but games as well and not just for the Android platform as they have had many of these across several platforms in the past.
G1-ers may now navigate to Phoload and download apps directly through the browser and store them on their memory card. G1-ers can also rate, view and even recommend any software that they download.
