Hello friend.pahele to me bata du ki I phone brand hi kuch esa he ki isaki product har koi lena chahega . kyoki isake jesa softwar or isake jesi system or koi company wale nahi dete . iphone 4S me karib 2 year se use karta hu bat kabhi phone heng nahi huva aj tak ke kabhi koi problam aya ho. isaka 4 inch ka display or isaki desine itani great he ki ekdum jakkas piase lagta he . I phone ka prosseser iatana achha he ki kabhi phone heng nahi hoga ye mera khud ka expriance he meto jab bhi me fon change karunga to I phone hi lunga kyoki isake jesi system or prosseser or with inbilt memory or koi nahi dega.
