iPhone accidentally removed ipod app [Help!]

ive been snooping around trying to solve this on my own as i am truly ashamed . So i ended up asking for help as i reached my limit . First of all , Hello to everyone around here !
I got an iphone 4 from a friend a few weeks back , its my 1st apple product and since he was using it for about 2 years now i had to start " cleaning " it so i can get the best out of it " iphone 4 jailbroken ios : 4.3.2 " oh and it has a gevey thingy . I was thinking about upgrading it to 7.1 but that might make the gevey useless ..so i'll lose the phone all together as it will be locked .
I found out about ifunbox , and of course i had to start cleaning stuff up while using it , wanted to get rid of the old youtube app , stocks and all of that.
So i did , unfortunately i also ended up deleting " musicplayer " cuz i knew ipod was the default music player in the iphone ...thought it might be something else so i got rid of it , 2 more app's in the process as well since they had no real "icon " .. just a white image , making me think they were not functional anymore.
When i finally realized i can't play music anymore , and after i panicked for a few minutes ...i started searching google for any kind of help .
So i tried to backup and it didn't help at all cuz i managed to screw that up as well " a new backup was made before i realized ipod was missing .
After a few hours of searching , i found a bit of help ... what i did was i downloaded the 4.3.2 IOS and then using cmod and a few tips , i extracted its content onto my computer .
So the next step was to find " ipod app " in the applications folder , so i did ..and i copied it , but of course it did not work ..hence the reason i ended up writing to you good people from around here .
I used iFunbox for everything i did , i also installed SSH in the meantime thinking the new app might need permission to run .
Spent all day doing only this , any kind of help would be greatly appreciated !

Im sorry for being noobish and stupid ..and sorry about my poor english
