Samsung omnia i900 users?

[Destiny S]

Okay i have a BIG problem. I have a samsung omnia i900. and i have no idea have to use it. this is my first touch Screen phone. and it sucks because its a tough phone to figure out w/o instructions. but okay.. when i purchased the phone they just gave me the phone and that's it. and the box. and they wrote my number on a small sheet of paper. i went on the internet and looked for instructions and got them... found out some new things. BUT from me messing around trying to "Figure out" things i done blocked the internet some how...using "cellular line" .... do u think if i reset the hole phone everything will go back to the way it was when the people gave it to me? or should i try something else....PLZ help cause i love this phone and i hate that i have all these things i can do but don't know how or cant cause my internet is screwed....*( oh! and yes i do pay for my internet)* and yes i went to the place to ask for the booklet and everything but then they said that the phone was "USED" and when i had bought the phone they never said such thing if they did i def. would not have bought the phone!!! i mean the phone cost me about 312.00 dollars i didn't even expect it to be used being that price!! but anyone have ideas?
