Hard to use Camera & Inability to transfer contacts via bluetooth.

I have 2 issues;

1. I cannot transfer my old contact list from my Samsung to my Iphone

2. When I switch on the camer, i am able to take one shot then it freezes until I go to settings does it come on again. To sort this out I installed SmugMug Camera which also seems to have teh same issue of not working flawlessly.

Kindly help!

Regards.

John
