I got my iPhone 4 a few weeks ago fitted a
shield day after (a cheaper £6.99)
one I found on amazon as I hate using cases.it also came with side shields.not easy to fit but!!
Result is amazing other day got up from sofa phone went flying landed on a plate!(breath held!!)
plate smashed into 3peices!
Looked at it closely working fine although there was a mark on back I thought it was glass cracked under it so lifted shield and....
Shield has 1 small scratch along it but compared to my housing being cracked totally worth £6.99 for saving a £600 iPhone
Yes I know I should be more carful and will do infuture but accidents happen!
Would highly recommend anyone to fit there iPhone with one of any model.zigzags make is expensive so shop around
