I hope you understand my English.
Yes That's The Reason!!
by switching your sim card,the wallpaper and screen lock wall will change!!
and even when you switch it,even the sms will be send via that number with 3rd party sms apps Like Go SMS
i.e. if u select sim 2 and rply a sms, go sms will send your MSG by the second SIM Num!! LOL
