I'm curious as to how a jailbreaked iPod Touch would compare to e.g. the application (and application capabilities) of smartphones such as the Nokia N73/E51. At the moment I have a crappy Sony Ericsson k500i so I'm curious as to how applications are handled on the different platforms (yes obviously the iPod Touch doesn't the cellular features), my k500i just seems to do calendar and notes. Are there more apps available on the "mobile phone" smartphones? Does one platform allow more sophisticated applications? Sorry for the all questions!!
