first off, im new to the forums so hello everybody!!

im planning on picking up an omnia soon and i have some questions before i buy. main reason i want a iphone is because of the applications that can be downloaded for free, does the omnia have something similar to this? (keyword: FREE). also can youtube videos be watched on this phone? is the GPS included in the data plan or would that be an extra fee? TIA

PS - this is for a verizon account.
