Someone mentioned in another thread about sharing the Apps update if you purchased it, on other iPod Touch's using the same PC. Is this true? I can get non-updated 8gb Touches for $279 with an additional $50 Target gift card right now. The Touch WITH the Apps update is also on sale, but obviously $20 more ($299 less the $50). Since I've already got one, and my wife wants one, will the fact that I've paid for the update allow me to set up her Touch and get it updated for free?
