total newbie from walsall england

Hi to everyone
been learning for a month now, enjoying it & getting there slowly. Got afew questions that might seem stupid but im new first am learning with a 10 hole in C. I also bought a cheap spare off ebay just to mess with , it came and is alot longer than other and has 2 rows of 16 holes, and sounds quite tinny. I have given up with it so not to confuse me. What type is it, should I bin it or will it be useful as l get better.
Also have been getting used to playing single notes, the way that suited me best was by U blocking with my tounge. I have got used to this now. My question is now I am trying to learn to bend can I bend notes if im doing this ?
any answers would be great
cheers paul
