App compatibility for first gen iPod touch I have recently acquired a first-gen iPod touch updated to iOS 3.3. I'm having trouble installing apps from iTunes as it appears most require iOS 4 and above. So far I have managed to find two games that are still compatible with iOS 3. Not even the Facebook app will install! iTunes says I have the latest iOS available installed.

Is there a way to force install iOS 4? Otherwise, is there a third party repository of older apps I can install from (obviously after jailbreaking)?
You can use iOSSearch, a free tool to find apps in the iTunes store which are compatible with iOS 3.1.3. This is a non-commercial page I made.

Note: the app store has recently been updated to allow downloads of last compatible versions but it appears that this only provides apps which are compatible with iOS 4.
