hi nashith, just wanted to ask you. you know the ghost sim are you having any problems with it. im thinking about buying it but I want to 1. make sure it fits in the n900 sim cradle. 2. Do you need to configure anything or does it require another phone 3. And i have a t-mobile contract sim which uses internet so will it still work. 4. Last but not least one of the sims is bigger than the other so should i worry i know it a lot of question but if you could get back to me id appreacite it many thanks
