Xperia Pro MK16i/a 2.3.4 update 4.0.2.A.0.58

[Kaatje]

I've tried a couple of times to update my Xperia Pro from Android 2.3.4 to Android 4.0 with the PC companion.

Every time the PC companion says, I already have the latest software. build-number: 4.0.2.A.0.62. android 2.3.4.

Who knows how I can update my phone?
