Having A Reallllllly Hard Time Choosing Between The Iphone 4 And Samsung Galaxy S!!?

Iphone 4 or Samsung Galaxy S?
I’m having a lot of difficulty (and i mean alot) choosing between the Samsung Galaxy S and Iphone 4. No matter how many reviews i read, it makes the choice harder lol. Samsung galaxy sounds great but the poor battery, exterior design and not as great quality apps as iphone 4 does. The iphone 4 has reception issues but i don’t mind putting a case on it. I generally get 2 out of 4 bars reception currently and i’m worried if i get the iphone it will be worse.
I am looking for a phone that is entertaining as well as one that provides convenient access to facebook. I also text alot but calling is important too obviously!I don’t need a mobile much for any type of business purpose. Camera would be nice but isn’t overly important to me because i have a seperate canon camera.
