Parsing Feed Rss su Virtual Device funzione, su Galaxy S e Y no

[mic87xp1]

Salve a tutti, volevo parlarvi di un problema strano.
Ho trovato su internet una guida dove spiegava come realizzare un parser per feed rss.
Seguendo la guida, sono riuscito a scriver un parser che mette in una listview i feed rss.
Ho collegato il Galaxy S un Debug mode, mentre al Galaxy Y ho solo mandato l'Apk firmato via bluetooth.
Nel Virtual Device il parser funziona, sul Galaxy S no. Mi Da' un errore come se non ci fosse connessione ad internet, eppure la wifi sul Galaxy S è collegata al router e funziona.

Vi allego il codice Java e il logcat del Galaxy S
