I Bought Wrong Cellphone (i think...)

Few months ago, I bought new cellphone. But I think I choose the wrong one. Since it was a cheap phone, there are few features that can not be change even if I download the program from the Internet. Argh...maybe that's why we should not buy cheap product easily without knowing the quality of the product. Now, I can't do anything anymore. If I sell this phone and buy a new one, of course I need to pay more for a good phone. And on top of that, the price for selling this phone will not be the same with the buying price.

This is really useless!
