For one thing, mobile phone reviews do not get cash credits since these are freely available anywhere and also the content is usually not unique. Regarding other products and stuff, you will have to be specific about it.
I think this is one feature which would never be identified for unique so they only provide points for your efforts.
I don't know
IT is given before now also they are giving cc to reviews.
Even I thinks that mobile reviews are available easily at everywhere.. and it is going to be same at every place. So may be they are not that unique as articles.
There are no cash credits given for mobile reviews. Cash credits are meant for restaurant reviews.
Only for restaurants cash credits are given.
