I have unlocked* my 1.1.2. OTB iphone using a NextSim but I have run into a problem with data from my old SIM.

Now I realise that the iphone doesn't officially read data off SIMs but I have managed to copy my contacts over using a program called iSim. What I am trying to do now is to copy my SMS over with, I'm assuming, some 3rd party software.

I would appreciate it if anyone could let me know of an application that will do this, or even a different solution to the issue. Thanks in advance.

*Yes I realise I shouldn't call it unlocking but I'm stuck for words!
