The thing with the phones works differently atleast here in germany. Depending on contract size t-mobile or others shell out a provision upto ranging from 100-500 eur per contract. you basically pay this back by less favorable phone costs or higher monthly fees with 2 contracts you can get 800+ eur as provision. the seller usually gives 2 decent smartphones with it but he can also give 2 not so good phones and a ps 3 or notebook or in some cases a motorscooter.
Those promotions have nothing to do with sony those sellers usually buy large quantities of ps 3 wii tvs notebooks xbox 360 and give it away with phone contracts. Sony has usually nothing to do with it afaik.
a similar deal to win 7 pc + xbox 360 would be sony bravia tv +ps 3 .
