Update apns-conf.xml

For Argentina, Movistar AR is mispelled
<apn carrier="Movistar AR" mcc="722" mnc="07" apn="wap.gprs.unifon.com.ar" proxy="200.5.86.10" port="80" user="wap" password="wap" authenticationtype="PAP" type="defaul,supl" />
Instead it should be
<apn carrier="Movistar AR" mcc="722" mnc="07" apn="wap.gprs.unifon.com.ar" proxy="200.5.68.10" port="8080" user="wap" password="wap" authenticationtype="PAP" type="default,supl" />

Also, another user can be added.
<apn carrier="Movistar AR Internet" mcc="722" mnc="07" apn="internet.gprs.unifon.com.ar" proxy="200.5.68.10" port="8080" user="internet" password="internet" authenticationtype="PAP" type="default,supl" />

Thanks!
